Designed exclusively for Performance Bicycle, the Giro Sotto road shoe provides some of the highest technology and forward thinking engineering you'll find in any pair of road shoes. The goal of the Sotto is to provide a comfortable, efficient shoe at an excellent value. To that end, the Sotto utilizes a DuPont Zytel nylon sole, which offers amazing stiffness and improves fatigue resistance over other nylon-soled shoes. A microfiber upper provides plenty of support, while also being highly breathable. Molded EVA footbeds with antimicrobial treatment and a neutral, medium-height arch support improves pedaling efficiency. The Sotto also borrows the Precision Fit last from Giro's top-flight ProLight SLX and Trans shoes so you get a great fit that will keep you comfortable for mile after mile. A ratcheting buckle and offset hook and loop straps help keep your foot locked into the shoe.
