Nike Alphafly Next% and Vaporfly Next% 2 Racers - Available (again) now I use the Vaporfly 2 and they are noticeably faster than any other road shoe I've ever used. It seems to me that the Prebax foam is what delivers the benefit but it could be the carbon inserts as well. The Alphafly will be much the same, maybe better I haven't tried them yet. I'm currently trying to either get hold of the competing adidas Prime X or adidas Adios Pro 2.0 but I'm not having much luck there as they are out of stock although due in 'soon'. So for now you can get the super speedy Nikes directly from Nike.com and/or check out my review below which is a decent read.
