Black Diamond's Freeride Series boots come standard with DIN-certified Alpine Sole Blocks, which are meant to be used with standard alpine bindings. Black Diamond Alpine Touring Sole Blocks may be used interchangeably at the user's discretion; these feature a full rubber sole with a deep tread and are optimized for grip in cold temperatures. They are compatible with ISO Touring spec bindings, and also include tech fittings for use with tech (Dynafit-type) bindings.
