The Belgian Bootie 4 serves Castelli’s pros well from cool fall road rides all the way through winter to the ‘cross spring classics. While that’s fine for the pros, the Belgian Bootie 4 gives the self-sponsored one feature that the pros don’t share—four different colorways to choose from.
Castelli Belgian Bootie 4 shoe covers are made with snug-fitting polypropylene that insults without bulk, so they won’t rub your crankarms while you ride. They are also tall enough to cover your socks to keep out moisture and mud. Cleat and heel cutouts make it easy to clip in and scramble over obstacles, and reflective trim makes you more visible in traffic.
