These are the oversocks worn by Mathieu van der Poel and the entire Alpecin-Deceuninck team. They have been ridden to victory many times, including the Tour of Flanders, Gravel World Championships and Milan San Remo. 

• 2x leg grippers to ensure a non-slip grip. Spatz have added a very sticky silicone tape to the hem, in addition to a woven-in silicone gripper. We do not know of another manufacturer who has gone to these levels to ensure a good fit on the legs.

• Striated, aero fabric is cut and tuned to follow the contours of the ankle joint and articulate beautifully without wrinkling or creasing during the pedal stroke.

• Cut tall to meet UCI length regulations.

• A very tough velcro fastener tucks neatly behind the cleat/pedal interface to allow easy wearing, tuning of fit and an aerodynamic silhouette.

• Kevlar toe area to avoid nicks and tears to the fabric. This is another first in Aero Overshoe design.

• Silicone grippers have been placed inside the heel area to lock the booties solid against your shoes. They will not "ride up" your heels during a race situation.
