I know it's the WRONG thread, but just my surprising n=1 today - I've been doing 1x/wk intervals with Endorphon speeds, which probably have 100ish miles on them over 10-11 wks, and today I tried the new Vaporfly next 4% for the first time........................
I'm convinced - there is NO way this could have been placebo effect for me - on even my HR data, I averaged 151HR on the Speeds and 148 on the Vaporflys.
Sorry bout the off-topic, just couldn't hold back the comparison
Here's the thing. You can have 20 people testing these VF or Pro's (which would be an apple to apple comparison) and you're going to see a time range of savings ranging from 1-7% with the VF being faster & near the top end of that range for some while the Pro's are faster and near the top end of the range for others and both shoes clogging the meat of the curve.
Glad they worked for you, but like aerodynamics it's 100% N=1 or if you're not going to take the time to test (and 1 track workout in each does not = a true test) play the odds by buying the shoe that feels the best to you when you have it on.
It's def true I didn't test (or try) the Endorphin Pro. They may indeed be as fast.
But I've been running and doing these painful track workouts long enough that I def know 'magic speed' when I see/feel it. The Endorphin Speeds (not pro) were light, nimble, and yes, feel great, but still no 'magic speed.' No other shoe I've used, even the ultraminimalist ones of virtually no weight, gave a legit speed bump.
The VF has been the only shoe I've tried that did it. And while I've only worn the VF once, I've done this same interval workout countless times in the past 2 years, and I know my expected paces for those efforts really, really well. I literally have never seen the speed I ran with those VF for those intervals, ever.
I much prefer the footbed of the Endorphin line (I have flat feet, and the VF has a big arch that feels super weird to me unless I'm running fast), so if I can try a Pro in-person I'll see how the bounce compares.
The VF for me is so 'bouncy' that you can feel it just walking around. It literally feels like springs under your footbed - you can feel the pop and bounceback even while walking.
