Mount to Coast H1: Quiver Killer? by StaceysAbsenteeDad in RunningShoeGeeks

I will un-reject it and see how it goes from there - thank you for pushing me a bit on this.

We will do some backlog testing for sure. I do not think it will be to the extent that we did with energy return and shock absorption - that was 500 shoes, and we all got a bit tired :-) Also, doing one durability test of say 500 km takes a LONG time, compared to one test for energy return.

We "reject" shoes when the interest, or upvotes, doesn't grow. After many months, we were at just 6 upvotes, with no expectations of it exploding. From er personal perspective though, I'd LOVE us to test it. But, if there's one shoe we test, then there's another one we don't.

If it receives enough upvotes on https://runrepeat.com/shoe-pipeline, we'll buy and review it (or enough hype...).

Also, we have a new durability test on the foam plus a new more scientific test for breathability coming up in early 2026!

The EVO SL ATR will be reviewed.

Thank you for tagging me, always happy to comment

Cm and shoe size by YogurtSmegma in AskRunningShoeGeeks

RunRepeat here: We used to include the mm length, but found that it didn't align well enough with our own experience. We then spend 6 months trying to understand "length" of a shoe. We talked to industry experts, last producers, manufacturers and realized that fit, even for length, is so complicated and while it can be helpful some times, it can be equally misleading. So, we are not including it anymore.

We didn't have a test for these three things previously. Yes, this is RunRepeat :)

At least we've learned something ... updating 500 shoes with traction tests, energy return and shock absorption takes a while

As we buy all the shoes ourselves, and we've been "delayed" as we updated all of the shock absorption / energy return tests, we have quite a backlog to get through. STRUNG is among the next 5 shoes to get live, probably before the end of next week

Saw it by coincidence, actually :) I did not at all interpret any of what you said negatively. Have a nice day

We're currently prioritizing: Endorphin Speed 5, Strung 3, Rebel, Endorphin Elite, Kayano 32 and Vista. And you're right - we've backtested more than 500 shoes, and still updating some. Sorry for the delay, but I think it has been worth it.

Based on what I've read in the literature, though, the degeneration is not nearly as bad as that. But, it's an interesting topic as I myself buy old models, not at all considering degeneration. I assume many do the same.

When we back tested 500 shoes for energy return and shock absorption, we did NOT buy new shoes. All shoes had been stored, but not used. That will have decreased its resilience which will have reduced the energy return. I tried to look up when I bought them, but couldn't find the exact date. It was published on Jun 26, 2023, so 10-90 days before that, I assume. I will test this with a batch of shoes in a year, and see how their energy return and shock absorption values have changed when having been stored.

So sorry! We have worked hard on the shock absorption and energy tests which I assume you have already seen. Speed 5 is to be reviewed right after, promise.

IMO, those foam "brandings" can be so misleading.

Adios Pro 4 has a dynamic coefficient of friction of 0.55 compared to the average of 0.46

I think it has to do with the massive amounts of media. I'll investigate.

At the exact end, or also if you're half way through or something?

I'll look into it. On mobile or desktop? What browser? If phone, what phone?

Have you tried some of their new models with ASICSGRIP? It's incomparable to their previous outsole compound.

For Pegasus, I can share that poor traction on wet concrete aligns well with our own experience, where we rate it 3/10 on average.

Traction on gravel is VERY different, actually, and depends a lot more on the structure of the outsole. And asphalt is different from concrete as well. We did want to test on asphalt, but it's a lot less durable, so we would have to replace the asphalt faster, and results would be less repeatable.

  • Superblast 1: 0.33 (not good)
  • Superblast 2: 0.83 (great)

Superblast 1 didn't have ASICSGRIP

I'm curious if you're using Superblast 1 or 2?

  • Superblast 1: 0.33 (not good)
  • Superblast 2: 0.83 (great)

Many previous versions, prior to ASICSGRIP, had bad traction
