I mean, this topic has gotten a ton of coverage but I'll still add in some of my usual thoughts. Shoes, alone, don't account for all of the improvement. Training, conditions, recovery, etc., all matter. Pacing matters. You're not gonna run 4% faster if you go out faster than you should.
Elite marathoners were getting ~90s-2:00 bump. Less than that for half marathon & under. Then there's the matter of what super shoes you're wearing & how well you respond to them. Labrat rundown found a 3% running economy boost from the Alphafly's. Now who on here knows if they're getting that full 3% or something different? A 36 minute 10k runner is not a 34 minute 10k runner because they put the shoes on. Maybe they were always a 34 minute runner or learned how to train/race. With a 36 minute 10k, there's still a lot of time on the table from better training. We're almost never getting the perfect recipe for races -- 40-50 degrees, no wind, well rested/recovered, uninterrupted training block, coming off a taper, etc.
The shoe talk is taking away from good performances. Yes, they help. But you still have to go out & execute.
