Every piece of a skate shoe matters, and etnies carefully designs each style to improve overall performance. The skateboarder-owned brand pushed the envelope even farther by including STI Evolution Foam™ midsoles and outsoles in this collection. STI Evolution Foam™ replaces your typical EVA, PU and heavy rubber with a durable, abrasion-resistant, ultra-lightweight and high-impact rebound cushioning foam. The foam technologyis used as a single solution for the midsole, yet its molecular build is more resistant to abrasion and has a high-impact rebound quality so it won’t pack out when landing hard. Instead of being die-cut from a sheet, STI Evolution Foam™ midsoles are made by a special molding process, producing no waste. Plus, STI Evolution Foam™ enhances the cushioning and comfort of the footbed and noticeably decreases the weight of the shoe. That’s a lot of performance-driven features in a single piece of foam.
