Chasing 100 - 5 adidas athletes will attempt to be 1st to run 100k in under 6 hrs using a 60mm illegal shoe (Pics) on August 26th

Here is some more info on the run and the shoe being used:

The shoe is totally wild looking:

Ahead of an attempt to break the 100km world record, the German sportswear company teased a running shoe unlike anything else to date.

I twisted both ankles and got shin splints from just looking at these shoes. 60mm??

Good shoes are not the problem at a 100k race.

Such a waste of a big record attempt if all the athletes are running in ILLEGAL footwear. Just a marketing exercise for a brand. So stupid and disrespectful to the sport!

This is your chance, can one of the 50 american marathoners that are capable of breaking this record, please go to your local park and break this record before the event.

I mean, they could just drive the 100k.

This makes a lot of sense for the shoe brands to do. I thought there would be something more like this for Kipyegon's record attempt. There is no such thing as an "illegal" shoe, just a shoe that won't be eligible for records. The running shoe market is 99.99% comprised of people who will never run fast enough for that to matter.

Stunts/promotional events like this that get people talking about how ridiculous the shoes are before the event will pay off tremendously if/when the "records" get broken in their shoe. Then the post hoc analysis will give credit to the shoes, and there will be a ton of hobby joggers like myself trying to squeeze out a sub-20 5k or others looking for a BQ who will look at these shoes and think "hey maybe it's worth it". There's a lot of money here.

I'm pretty sure those could be worn for high school races in my state.

That thing doesn't look wild, it looks ridiculous

They need a world record to sell them. People buy running shoes to wear around in everyday life, but not these ones

Sadly, this is probably true.

mind as well load up on as much EPO as you can find too

Sorry, dude, but the phrase is "might as well" not "mind as well"

American, right? Do you say "could care less" too?

If we want to market the sport of ultrarunning better then we should not be having sponsored athletes running in such ridiculously ugly shoes...

Looks like something Gene Simmons would wear.

That shoe is nuts, cray cray

Great! I'll be on the sidelines with a crate of super dildos throwing them on the course. Make em' work for that WR!

Zzz

More is better only works to a point. At least one study was done that determined excessive increases in stack (60 mm in this study) didn't improve running economy (metabolic power), however, the study was done on nitrogen infused midsole and EVA midsole shoes. I would submit that different foams, plate configurations, soled geometries, surfaces used on, etc., should have different optimal stacks.

Effects of midsole stack height and foam on the metabolic cost of running
Montgomery Bertschya, Herlandt Linoa, Laura Healey and Wouter Hoogkamer

Methods:

Two sets of weight-matched
footwear conditions were worn (part A: 30mm
EVA, 40mm EVA, 60mm EVA; part B: 30mm
EVA, 30mm NITRO, 60mm NITRO)

Results
Within the EVA midsole material (part A), larger
stack height led to a non-significant increase in
metabolic power (0.4% increase per 10mm,
p=0.12; Figure 1). Within the NITRO material
(part B), larger stack height led to a non-significant
decrease in metabolic power (0.13% decrease per
10mm, p=0.052).

Christian Louboutin better watch out. Looks like there is a new player in the high heel space.
