I am curious, would the Next% have noticeable impact over distances such as 3k, 2mi? Or are those too short for the shoes to play a role.
Additionally I see over the internet various homemade Next% with spike plate. How much is that really making a difference on a track for a shorter race such as 3k.
Discus.
it has the same impact at any distance: 4%
but it's not 4% faster, it's 4% more efficient. are you running into energy efficiency issues at those distances?
I think a big factor here is that it will be different for different runners.
For runners that arePretty efficient with flats or spikes, they may not make a difference at all.
I plan on using them this year for track races as little as the mile . But I’m a Masters runner and don’t really like wearing light racing flats.
I particularly like the fact that when you run with them it causes you to run more on the front of your foot and you get that extra little push off.
That said, I don’t see too many of the high school and or college runners using them in a 2 mile race.
I recently ran a 5k time trial in Next %. I felt like hey didn't help me at all, and I didn't feel like I could go as fast in them when kicking to the finish. For a time trial, they were just right because I got a good gauge of my fitness without the pounding of spikes, so that was good. For me, i'd go with spikes for racing under 10k.
