Expanding the area of protection even further down the foot; System G2O2 Full Impact™ stretches underneath your foot’s arch area to protect against heel bruising and harsh landings while skateboarding. The soft half-length System O2™ air bag absorbs low impact forces associated with flat ground skateboarding, while the System G2™ gel kicks in when higher impact forces are experienced on terrain such as stairs and skatepark jumps. The result is the ultimate skateboarding cushioning technology that absorbs up to 85% more force than conventional skate shoes.
