System G2O2™ combines the success of System G2™ with a System O2™ air bag to provide dual cushioning protection for the heel during all types of skateboarding and snowboarding riding conditions. The soft System O2™ air bag absorbs low impact forces associated with flat ground skateboarding or snowboard terrain and free riding, while the System G2™ gel kicks in when higher impact forces are experienced on such terrain as stairs and park jumps.
The result is the ultimate skateboard and snowboard cushioning technology that absorbs 10 percent more force than our already popular System G2™ cushioning technology. For its efforts, STI received the first-ever action sports related cushioning system patent for footwear in the history of the skateboarding industry for System G2O2™ – U.S. patent 7,020,988 (Download Patent PDF).
