Fastest Tech Doping Running Shoe?

Hey all,

I know that the alpha-fly and vapor-fly have been discussed at length in this sub, but I’m having a hard time figuring out what the best/ “fastest” shoe is by statistic.

It will be for a timed 1.5 mile run, and I keep seeing that the vapor-fly is best for shorter distances. However, if the alpha is just that much better or can help produce a faster run, then that is what I would end up going with.

Or, if there’s even something better than both of those choices, I would really appreciate the help!
