Northwave's Sonic Tech SRS Shoes pull no punches when it comes to performance and breathability. The carbon light soles transfer all your power to the pedals, while comfort comes in the form of the polyurethane upper with Northwave's AirFlow that stays snug over your feet and keeps air moving through the shoes. Their Slim Ratchet System and two hook-and-loop straps deliver even pressure distribution and quick adjustment, and make for a great fit.
