Loss of power transfer can add up over a long ride, which is why a rider's foot must properly integrate with the shoe. Convert wasted energy into extra speed with the Giro SN Women's Footbed X-Static Kit. An adjustable arch support system lets riders select their own level of support, while the Kit's low profile helps keep your foot close to the pedal. X-Static fibers offer an antimicrobial touch so you don't have to worry about smelly shoes after the race.
