Shoe Review: Newton Running MV3 Racing Flats / Trainers

You’ll see from several previous posts that I first looked in to whether racing flats really make that much difference and secondly, a look at my shortlist of the five best racing flats around in 2014.

Well… I finally decided on going for some Newton MV3′s. Newton call this a ‘lightweight performance racer’ and at 5.4 ounces they really are. I think my flip flops  (thongs to you guys in the US) weigh more. I think I have socks actually that weigh more! The mesh upper is barely there. When you’re running, you kind of forget you’re wearing shoes and, after wearing heavily cushioned Nike Lunar Glides for two years, I could suddenly actually feel the road beneath my feet.

Heel Drop

These shoes have a zero drop and with the five lugs at the front they feel like they have a slight raise at the front even. They do come with inserts to raise the heel by 3mm for a gradual adjustment if required. I haven’t inserted these yet, but having done a 7.5k test run earlier my left Achilles is definitely sore as is my right calf. I may therefore add them before the next run. I can see why some people say these are only good to wear up to half marathon distance… Newton even have a ‘good running form‘ guide on their website to help you run right:

Sizing

One of the worries with ultralight racers is sizing as they generally seem to be a snug fit. I run a size 9 in my Nikes so after checking with a Newton rep which size I should go for, he recommended to go a full size up to a 10. Well the shoes arrived on the same day I had a track speed session to go to, but no matter how optimistically I looked at the huge gap between the end of my big toe and the front of the shoe, the phrase ‘clown feet’ kept entering my mind. So I sent them back on the Thursday and by 9am Monday I had a new pair of size 9′s. I went for a run in these today. They felt ever so slightly small on first try but after just a couple of km I felt I was running barefoot but with trampolines on my toes!

In Summary

It took a LOT of research getting to the point of actually ordering the Newtons and I have to say I’m pretty pleased with them. Super light and they look the part too if I’m honest – looks shouldn’t matter but of course they do! When running with them I could feel the shoes urging me to run raster with the Action/Reaction tech.

Training: A Fast 5k and Newton MV3 Sizing Issues!

Tuesday arrived and with it the promise of a new pair of racing flats (more on those later) and an evening speed session on the track. Rushing in the door from work, whilst my wife rushed out the door to go to her running club I spotted a package with my name on!

New Shoes (Upset Number 1)

Taking out my gleaming new Newton MV3′s from the box, I brimmed with excitement as I felt their weight. So, so light and very minimal upper. I was advised by Newton to order a full size up from my usual 9, to a 10 which I duely did… And regretted. Slipping the Newtons on they instantly felt too big. Optimistically, I laced up the second shoe and mock-jogged and the house but there was definite slippage and so much space at the toe end, the show pinched my big toe with every take off. There was a good 2cm/half inch gap at the end of the trainer so reluctantly I put them back in the box to return them for a size 9. Width wise they felt perfect so I am slightly wary of how the 9s will feel here – watch this space!

Upset Number 2

The second disappointment of the day was rushing off to the track session and doing several warm up laps, before looking up and realising there wasn’t the usual smattering of people warming up. Realising it must have been cancelled I drove back home and headed out for a fast and furious 5k by myself! I’d just borrowed my dad’s Garmin heart monitor so my aim was to push to the limit and see what my maximum heart rate was.

I did 5k in 21 minutes (very hilly) and definitely got my heart rate to the max!

Next Training
10k this evening if I can fit it in!

Top 5 Racing Flats For Running in 2014 (Saucony A6, Nike Flyknit Racer, Newton MV3, Adidas Adizero Adios Boost & New Balance RC5000)

Top 5 Racing Flats – After a LOT of Research

As an ordinary Joe Runner I am often on the lookout for ways to improve my times other than the obvious HARD WORK!

As I’ve looked at in a previous post, racing flats may offer around a 1% increase in speed which although apparently trivial would make all the difference in my 5 and 10k races! Now I never purchase anything without first doing copious amounts of research into different manufacturers and models, reading reviews and comparing prices online.

I’ve recently spent so much time switching between tabs in my browser to compare the shortlisted trainers that I’d thought i’d be easier to list them all out here for all to see and to hopefully help save you the time I’ve spent looking!

1. Saucony A6 – Price £80 – Weight 144.6g

Weight is all important when looking at which racing flat to choose and the Saucony A6 is VERY light – 5.1 oz / 144.6g. The upper is a water shedding, airy mesh that Saucony call FlexiFilm, which apparently sheds moisture and heat as you run.

There is a rubber outsole, a foam EVA midsole to add cushioning and drainholes in the sole that allow moisture to drain out through the bottom of the trainer. Some reviews I have read say this has the potential for gravel to get stuck in the holes and for water to actually leak IN through the soles.

One reviewer said these shoes BEG to go fast and that you can’t help but run faster in them due to the design!

In research the fit, it seems that the sizing of the A6 is spot on for most people with no requirement to size up or down a half or full size. Plus they look great – these are the ones I went for in the end, mainly due to the hugely positive review on Running Shoes Guru (my fave website!), but also because they come in at the mid range price of £80.

I found them cheapest in the UK and in stock at Wiggle. More on the Saucony blog

In Summary

One of the lightest shoes on the market, still has a slight heel to toe drop and competitively priced – these will be mine, oh yes, they will be mine.

Nike Flyknit Racer – Price £129.99 – Weight 159g

Now these shoes look good! They really are where fashion meets function and I think in the end that’s what swing my decision away from them. Well that and the price. These trainers are for sale on fashion sites like ASOS as well as your regular running shops. I’m no running snob (ok maybe I am) but for some reason I don’t trust a shoe that isn’t worn purely for performance.

It’s clear that the Flyknit technology is excellent and helps with the lightness and sock-like feel of the shoe, but all the different colourways make it seem too fashiony for my liking. Hell, they were launched at Milan Fashion Week! When you read the comments on the Nike website to get a feel for how they perform, it’s just a load of fashionistas commenting on the colours and look of the shoe – bleugh.

One thing this model does have going for it; these are Mo Farah’s go to shoes for the marathon distance

In Summary

I does look good, it’s very light and many reviews say that they are very comfortable, but for that price range I decided against.

Newton MV3 – Price £110 – Weight 5.4 oz (142.8g)

Newton call this ‘the lightest running shoe ever produced’ which, when looking at the others on this list holds true. My decision to get racing flats was kickstarted after running alongside someone who was wearing Newton MV2′s. Her running form was far better than mine and she swore blind it was all down to the technology in the Newtons, forcing her to strike on to her forefoot.

Newton seem to have gained a reputation for taking a more scientific approach to show design and the majority of the innovation appears to be in the mid-sole. This is what it says on their website:

MIDSOLE

  • Second generation Action/ReactionTM technology in the midfoot
  • Biomechanical metatarsal sensor plate
  • High-rebound EVA
  • Met-flex enhanced midfoot flexibility
  • ETC anti-friction, antibacterial sock liner
  • Water drainage system
  • Optional 3mm lift included
  • Widened midfoot and filled toe area for greater stability

In Summary

I did seriously consider getting these as they are created precisely for what I need – a 5-10k racer. However, they have a zero millimetre drop which I think may be too much of a change from my Nike Lunarglide 5′s which have a large drop and lots of cushioning. These may be a shoe that I move on to once my joints have gotten used to running on racing flats.

Adidas Adios Boosts – Price £98.99 – Weight 220g (7.7oz)

In comparison to the Newtons (0mm), these racers have a 10mm drop which seems very high for a racing flat. However this drop incorporates the Boost technology that Adidas have been heavily marketing recently.

At the pre-London Marathon expo Adidas had a display that had my son entranced… The floor of the left hand part of the display was  made from standard EVA foam, whereas the right hand floor was made from Adidas’ Boost foam. Over and over again a metal ball was dropped from a height of around 1 metre on to each of the surfaces, showing the resultant bounce. The Adidas Boost foam definitely made the ball bounce a lot higher. To what extent this translates to real world running I’m not sure. Steve Way, 100k World Champion and 2:16 London Marathoner is sponsored by Adidas and these are his shoe of choice.

In Summary

This is a nice looking shoe and the Boost technology is very appealing. However the high price and the fact that it’s not the lightest racing flat go against it. After owning Nike Lunarglide 4′s, I ordered a pair of Adidas Boosts in January this year but they were so uncomfortable a fit that I sent them straight back and opted for the Lunarglide 5′s.

New Balance RC5000 – Price £81.99 – Weight 3.2oz (85 grams)

These shoes are an older model and are ridiculously light at just 3.2 ounces! They kind of disprove Newton’s assertion that they make the lightest running shoes ever! With a 6mm drop they are not too flat and not too high. With a super thin upper these are a true minimalist running shoes! Weight loss is found through the minimal cushioning in the midsole which may give a slightly harder ride but that’s the the compromise – heavier Adidas with lots of cushioning, or extremely light New Balance RC5000′s with less.

The sole also has rubber spikes which should give excellent adhesion to the road or track, saving micro-calories of energy through the lack of slippage on each take-off.

In Summary

Really light at 3.2 ounces, great grip and nowhere near as expensive as the Nikes?! These may actually be a contender for me.

If you use them, what’s your go-to racing flat?

Do Racing Flats Help You Run Faster?

One of my missions this year is to run a 5k PB and, ultimately, break the 18 minute mark for this distance.

As I was at the start line of Parkrun a couple of weeks ago, I overheard two speedy gents discussing one of their new ‘racing flats’. The guy who was wearing them swore blind that they were the reason for his 5k PB the week before…

So as ever, I like to investigate these things!

The first piece of info I found states:

“Multiple researchers have found that increasing shoe weight by 3.5 ounces increases oxygen uptake—the energy needed to run a certain speed—by about 1 percent. Translated, this means shaving 3.5 ounces off a pair of shoes is equivalent to increasing your run fitness by 1 percent.”

Ok great, so that means getting a lighter shoe will improve my time by one percent? What’s the use in that you might ask (as I did)?

Well think about all that training you do. I myself have been out training hard the last5 days straight to get an improvement on my times. I’ve been spending Sundays running miles and miles to achieve a better ‘core fitness’ as they say.

New Balance RC5000

I think it’s actually pretty amazing that just by putting on a different pair of shoes, you could take time off your PB. If you’re currently running a 40 minute 10k then a 1% decrease in time equates to running your 10k 24 seconds faster. If you’ve been trying to crack a sub-40 10k for a while then this could be your answer! If I were to wear racing flats in my Parkrun then I could knock 11.4 seconds off my time. I don’t know about anyone else, but I’ll take that! 11 seconds in a 5k is a HUGE amount.

Looking at the best racing flats, it appears that the New Balance RC5ooo (above) are pretty good. I prefer a trainer with a neutral ride so the Newton Energy NR also look good, gaining 5 stars on the highly regarded Running Shoes Guru site.

Running Gear: The Emperor’s New Compression Socks?

Do running compression socks work?

Do running compression socks work?

When I first started running a few years ago I didn’t even consider what socks to wear, or that this might make an actual difference to my performance. After a while, to avoid blisters, I started using specialist ankle running socks which felt fine but in real terms I probably could have kept on with my regular ‘sports’ socks and nothing would have been any different…

Then I noticed people at races wearing these really high socks… They went up to their knees! At first I thought perhaps this was a fashion thing that I really wasn’t getting but then I heard someone call them ‘compression socks’. Hmmm, I thought… that sounds scientific, maybe people are wearing these things for a reason!

I bought a pair and wore them for a few training runs before trying them out in a half marathon. I noticed no difference apart from blisters in places i’d never got them before. This is my investigation into whether compression socks for running actually work…

Possible benefits of compression socks:

A quick look at the description for some compression socks on sale promotes the benefits as:

  • More energy, greater endurance and enhanced performance thanks to improved blood circulation
  • Activates the flow of blood in the muscles
  • Muscle and joint stabilization for reduced risk of injury
  • Increased coordination by activating the muscles for a sense of stability and security when running

But surely they’re biased?!

During a Run – Maybe, Maybe Not!

Blood can pool in your legs. They’re low down so gravity tries to keep more blood than is necessary there. Your heart then has to work extra hard to get the blood up through your leg veins to be diffused with oxygen again and get rid of the lactic acid build up. It is suggested that wearing compression socks might increase venous blood flow, so flushing out these by -products of muscle exertion and warding off fatigue.

THERE IS NO CONSISTENCY in the results of the various studies done on this field. Ali et al. (2007) found that no performance or changes in physiological parameters occurred during or after a 10k run. In a more recent study,  Spurlich et al (2011) also found that compression “revealed no effects whatsoever”. On the other hand, Kremmier et al. (2009) found improved performance when wearing compression socks while running. The problem is that over all the various studies there were a lot of variables, from the type and length of socks, to the abilities and physiology of the studied athletes.

After a Run (Help the Recovery) – Probably!

There’s a theory that suggests that the vibrations created with every foot strike contributes to post-run muscle soreness. The aforementioned study by Ali et al. (2007)  “did find a reduction in muscle soreness, pointing to the muscle vibration and recovery aspects of socks.” Additionally, a study using full lower body graduated compression tights only after exercise showed improvements in muscle soreness (Byrne & Easton, 2010). so it would seem that compression socks CAN help your muscles recover quicker after a taxing run. As Steve Magness says though, it’s the process of damaging your muscle fibres and rebuilding them better adapted to running that helps improve fitness

Apparently the best types of compression socks to get are those that compress more down near the ankle, with compression force decreasing towards the knee. Buy them here (just for your info, I get no commission!)
