The Skate Fender Pro is molded in an even higher grade polycarbonate than the Standard model. They are slightly lighter, stronger, more flexible, and provide more impact energy dissipation. Skate Fender Pros will not only protect your skate from wear and tear, but they"ll protect your foot as well. No more limping off the ice after blocking a shot, no more missing shifts, and no more trips to the doctor. Sold in pairs, and currently available in two adult sizes: Small-Medium, which fit most skate boots from size 8 down to 5 (or even smaller depending on boot width and style) and Large, which fit most boots from size 8 and larger. Large size weighs approximately 190 grams each.
