Hey Runners, turns out that zero drop shoes result in negative heel angle on impact, excessively stretching your Achilles on every footstrike, according to a paper coming out this month in the Journal of Footwear Science. Vimazi builds a small drop into our shoes to prevent your heel from going negative. Shoe design backed by science!
