Honest personal feedback: how much faster are the best vaporfy/alphafly for you,personally?

I started running marathons in my late 40s in large part because of supershoes. At the time I was running in Kayanos and someone gave me a pair of Supershoes to motivate me. It worked. Honestly, I probably would not be nearly as into running as I am if I didn’t have the “race fast in the bouncy supershoes” event to look forward to.

So yes, I am a faster and better runner and weight 15lbs less.

This is hilarious. Okay so 3% improvement. A 5 minute mile (300 seconds) is now a 4:51 mile. So anyone who ran a 2:11:00 marathon would now be a 2:07:06 marathon runner. And anyone running 2:05:00 is now running Kipchoge's world record... Even though we had dozens of 2:05 runners before 'super shoes' and yet we still only have 3 runners to ever run sub 2:03. The math ain't mathing here

It's been a slight improvement for me. In early 2019 I was training for a HM in Adios 3, reasonably confident in setting out at 5:40m/m. I wore 4% in the race (for the first time), by mile 4 I felt a little too comfortable and pushed on, averaging around 5:35m/m for the whole thing. In marathons - Sep 18 I ran 2:36:01 (Berlin) then ran 2:34:05 (San Sebastian) the following year. Not sure how much was due to the shoes (Adios 3 to Vaporfly Next % v1) versus approximately 4000 miles of running between the races. I've found the Vaporfly have kept my calves in good nick for the last 3 or 4 miles of the marathon - in previous racing shoes my calves have felt unresponsive late on in a marathon. Side note: last year due to the pile-up of races following the pandemic I ran Berlin and London a week apart - both in 2:38. I would not have dared to run London like that if I'd be wearing my old Adios.

I honestly haven't seen a ton of improvement in the marathon but I also haven't raced one in good conditions in the super shoe era. I had good results in Boston in 2018 & 2021 on tough weather days. Guessing I would've been a little slower on those days.

You're supposed to get ~60-90s in a marathon but that implies good weather day, good pacing, good hydration, etc. I just saw a Facebook memory for Chicago 2013 where I went out at what my current PR pace is today. Almost held it & am certainly a lot better today than I was then. I think I'm due to shave off some time but the marathon is a tough distance. Need a good combination of factors or to race 2-3 every year in good conditions.

Super shoes have not made me faster but I definitely recover more easily after hard workouts/races. Maybe that's why I'm not getting faster?!

True but I should say that I had been improving year to year so maybe not all Of that was attributable to the shoes. At maximum, 4-5 seconds per mile but not the amount of time others are noting.
