People are way to fixated on Nike. Hoka stack heights have been in the upper 30s for years. The new Adidas is definitely more than 40. Hoka has a carbon plate in a high 30 stack shoe, do we see any ridiculous times in that shoe, no. But stack height is not the determining factor of a good fast shoe. What makes the vaporfly great is the combination of react foam and the plate. The lightness of React allows them a higher stack height at low overall weight. Personally I think all other brands, Adidas included are lightyears behind Nike. And now Rumour has it that the record breaking Alphafly is in fact a single plate shoe with a stack height less than 40. So we might see Kipchoges sub 2 shoe used in Tokyo. This would cause a copious amount of tears from the anti Nike crowd. Personally I will never race in anything else than Vaporflys again. Its just that amazing.
