The fastest covering for your feet, for the high speeds of time trialing.

Now even faster, the Fast Feet 2 TT Shoecover is the fastest foot covering for efforts against the clock. This shoecover was designed based on extensive modeling of the different aero demands of the foot and lower leg, followed by cylinder testing to identify the ideal shapes, and then extensive dynamic wind tunnel testing to fine-tune the fastest foot covering available.
