Has anyone actually tried these Vaporfly Next shoes that seem to have go faster stripes?
Notably Kipchoge and Kosgei in recent records.
My interest is not going quicker, I have slowed down far too much for that.
But I got the impression from some comments that the shoes , by reflecting energy rather than dissipating it, also have less impact so they may do less damage to legs and joints when running on hard surfaces.
Does anyone have a view?
