The Big and Tall Skates have the same toughness and slickness as the All Purpose Skates but just more of it! Not to mention the Big and Tall Skates have a higher wider heel which will eliminate the roll over. Meaning vehicles are less likely to roll over the skate with the tires when on the Roll Back or trailer. Dimensions 16″ L x 5 1/2″ W x 5 1/2″H. Cable loop on skate in designed for caring and storing purposes. Big and tall skates are sold in pairs.
