How to use: Slip your feet into the shoes. First, adjust the Powerstrap around your foot for a snug fit. Then, fine - tune the instep and midfoot areas according to your comfort. You're all set to hit the gravel roads! Note: Don't overtighten the straps as it may cause discomfort. When choosing a size, refer to Fizik's size chart. Maintenance: After each ride, wipe the shoes with a damp cloth to remove dirt. Let them air - dry. Avoid using harsh chemicals or putting them in the dryer, as this may damage the materials.
