System G2™ was the first technology ever developed by STI and also the first patented cushioning system in the history of action sports. Today it is recognized as simply being the best shock absorbing material that absorbs up to 20 percent more force than conventional skate shoes and snowboard boots.
Designed to help reduce injuries and prevent heel bruises, System G2™ is inserted into the heel and combined with EVA or PU to provide dual-cushioning comfort and protection that helps absorbs a wide range of forces, from 1 body weight when you're just standing around on your feet, to 18 body weights when you're bailing out from a 12-stair. If you go big make sure you have System G2™.View current products with System G2 »
System O2 is one of our original cushioning technologies. By encapsulating a thick air bag into the heel of PU foam midsole, System O2 provides a cushiony soft ride and maximum impact protection.View current products with System O2 »
Skaters feet can get hot and sweaty after just a few minutes of skating. System Flo2™ tongues are designed to let hot air escape out of your shoe and allow cool air to flow back in. Since a majority of your foot’s sweat glands are located on top of your foot, System Flo2™ tongues are placed in the exact location to provide maximum effectiveness.
Normal skateboarding tongues are made with layers of dense non–porous foams that are held together with thick layers of glue. System Flo2™ tongues are designed with minimal glue and breathable linings which increase air flow by up to 60%. Enjoy the comfort of cooler feet by trying out shoes with System Flo2™ tongues today!
Skateboarding requires the ultimate board feel and control. If your shoe and foot move independently from each other your performance will suffer. STI’s heel lock system was designed to keep your heel from slipping out while skating. The special anatomical shaped pads wrap around your heel to lock your foot down allowing you better feel and control of your board. Look for STI Heel Lock in select shoes.View current products with Heel Lock »
STI Evolution Foam
STI Evolution Foam™ replaces EVA, PU, and heavy rubber with a durable, impact resistant, and ultra lightweight cushioning foam that can be used as a single solution for the midsole and outsole of snowboard boots. This dramatically reduces the weight to create ThirtyTwo boots that are 15% to 40% lighter than previous seasons and remain the lightest in the industry.
