The Spider SRS mountain shoes have a sleek, updated appearance that just plain looks fast. They retain Sidi's traditional great fit, feel, and durability. The Spider SRS mountain shoe features a replaceable outsole with a new, reinforced toe. The Spider accepts a two-hole SPD type mountain cleat. The lugs on the sole keep the cleat recessed and provide plenty of traction when walking. The Lorica microfiber synthetic leather upper is extremely stretch resistant and durable. Venting is accomplished with mesh inserts. An Ultra SL buckle and two Velcro® provide precise closure pressure that stays consistent during rides without readjustment.
