Good contributions fuzzyduck and paulcook both.

Larkim, surely if your objection is only about "being true to yourself" you could just take the difference into account. I know you love your stats and analysis. Take a base reading of your time, heart rate etc. in your current shoes. Do same (a number of times to exclude outliers!) in super shoes, then you know how much the shoe is contributing (X%). Then go get your improvements in races, but only give yourself a pat on the back when it is more than X%.

Or is it truly (like me!) that you resent paying £200 for a pair of runners?! :-) G

We're all cheapskates in my family. I sent some goodies to my son and his family in an old shoe box. It had a price stick of £130 on the box and he slated me for it. In fact, they were 70 quid or less discounted in a sale and also were Inov-8 X-talons, high grip off road shoes for safety, not performance, so one of my few running luxury spends!

But as paulc said, bit of a tangent perhaps for Soapy's thread! :-) G

To answer the original question (how much have the shoes improved your times) ...well, it's complicated but taking my own performances as close to before and after swapping shoes to reduce the effects of different training load, age etc:

Marathon* 2:40:38 -> 2:30:26 (23.4sec/mile)
Half** 74:51 -> 71:12 (16.7sec/mile)
10k*** 34:10 -> 32:52 (12.6sec/mile)

Caveats:

*2:40 marathon was run in shoes that I now consider more like hiking shoes. Absolutely terrible for running and I would have been quicker in most other models. At the time I felt shoe choice had negligible impact on times, as long as they fitted ok and support was good enough.

**The slower time was on a pretty hilly course with nobody to work with after two miles, in racing flats. The quicker time was The Big Half, huge field, nice course, fairly good conditions

***The quicker 10k time was Telford (a course so quick I think it should be illegal, ultra quick downhill start and you never climb back up!) but I had raced hard for my club at XC the day before

The improved performances were all done wearing Next%. I trained a bit better in the lead up to the marathon and half, but not massively so. On balance, I rate Next% as worth 12-15sec/mile over my racing flats.

HappyG(rrr) I could do that but it does lack some precision! Much easier to just watch the clock. Plus how do I really know how much they work (or don't) for me? Nah, much easier to stick with what I've got.

I'm not an exorbitant spender on shoes, but I would justify them these days I think.

Jock,

I bought a pair of Gel-Kayano 16 back in 2010 when they were very highly rated. I paid £100 which was a lot back then, and still well above what I pay on average for running shoes. Think they were generally priced around £120-130.

Bought them mainly because a mate who was winning races wore them and I felt like I'd got fit enough to justify a proper pair of running shoes. Couldn't stand them! Far too soft on the inner sole - my shins were complaining after 2 miles, being made to work much harder through every landing/take off.

But someone local who is sub 2:50 without supershoes was doing all their races in Kayanos that I think they only paid £40ish for, so did Asics change them to a non premium shoe or was there always a big range of options?

Yep - I remember them being pricey at the time. I actually thought I needed a stability shoe but probably incorrect. If only eh !

So here’s an update. After all your valuable advice I bought a pair of ASICS metaspeed and ran Edinburgh parkrun wearing them. I ran 20:37, my first time under 21 minutes this year and for awhile before that. My previous SB was 21:02 so I was 25 seconds faster. Both times were set on flat courses on days without wind so I think the shoes definitely helped.

Got something to say?

At a recent race I noticed that about 90% of runners towards the front of the race - the fastest 10%- were wearing some sort of carbon plated rebound shoe. If you’ve got a pair of these, have they improved your race times ? How much of an improvement? Or is it all marketing and hype ?
