A strong and durable synthetic leather upper contributes to the lighter weight of the SH-RP100. When things get sweaty, the nylon mesh panels and vented sole keep your feet cool. Make adjustments on the fly with the double hook and loop strap closure. The secure fit eliminates hot spots and gives you more stability when youre on the attack.
