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% more force than our already popular System G2™ cushioning technology. Recently, 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. Boo-yah!
