Many traditional skateboard shoes and snowboard boots utilize either EVA or PU foams in the construction of their midsoles. EVA is lightweight, but it breaks down quickly. PU lasts longer, but is heavier. Both materials need heavy rubber outsoles to protect them from the harsh abrasive punishment skateboarders and snowboarders put their footwear through. This often leads to heavy and bulky skate shoes and snowboard boots that provide inadequate performance and protection. The solution? STI Evolution Foam™.
Engineered to function as both the midsole and outsole, STI Evolution Foam™ replaces EVA, PU and heavy rubber with a durable, long lasting, impact-resistant and ultra-lightweight cushioning material that can be used as a single solution for the midsole and outsole of skate shoes and snowboard boots. The results are shoes and boots that weigh up to 24% less than their traditional counterparts.
