Running shoes are funny things. Due to the fact that they are basically a weight at the end of a long fulcrum, the heavier they are the slower you will go. Plus they are full of padding which messes up the natural springs you already have built into your feet.
It is not surprising someone invented a shoe that is somewhat lighter which makes it faster. I find the spring idea somewhat dubious but maybe they do give you a slight boost. My question would be how fast you can run in these vs with no shoes on at all.
- lnanek2 8y agoVaporfly is actually heavier than some other racing flats that have performed worse, like the Nike Zoom Streak 6. So your theory of what is happening doesn't fit, unfortunately. Regenerative braking makes cars heavier and generally only returns 4-5% energy, but you don't see people demanding their electrics don't have it, do you? This is the same sort of thing for running shoes, but with energy returning foams and plates making their weight worthwhile for improving effectiveness instead.
- WhompingWindows 8y agoWouldn't a better control just be a typical running shoe? I don't see many serious runners running barefoot
- symmitchry 8y agoActually Noakes (I think it was) found that reducing weight was only effective to a point. Being barefoot is definitely not faster than having shoes on. See my other comment above re: Bikila.
