The duckbill shaped foot guard pads the toes, instep, and balls of the feet against the heavy strain encountered when attacking a hill, and during high intensity sprints. The special Silver NODOR® or SkinNODOR® and Mythlan fabric combination means that the fabric does not reduce space within the shoe. In addition, the special multi-filament design of the anti-bacterial materials traps air in its fibers. These tiny pockets of encased air protect against any pressure caused by the shoe, or the pedal. When the foot is called on to work hard it stretches and expands. In order to accommodate this swelling, the socks are made of a special knit rib material.
