I just used the Castelli Fast Feet Aero Sock last night in a race, and before I even got to the race, they were sliding down as my leg started to sweat from the ride. I had heard that the Castelli’s don’t stay in place well from a teammate, but I had already ordered them. No question that they feel fast when they are in place high and tight like they are meant to be. Unfortunately they became less than aero over the course of the race, and sure enough after the final sprint (came 2nd, nearly pipped 1st on the line), I looked down and the had fallen completely down around my ankle and were folded inside out. This is worse than just a regular compression sock!
Does anyone know of this issue and if there is a solution? How does Ineos keep them up for example on 6 hour stage races? I’ve heard some type of spray or something is used, but cannot find anything online, amazingly.
For the record, I had freshly shaved skin, and I did apply some Amp Human to the legs prior to putting on the socks. I don’t know if the Amp made things worse, better, or no difference. Either way, the single silicone gripper did not keep them in place.
