KNOW YOUR TECH breaks down the scientific technology used in your favorite sneakers and activewear. Let’s demystify your next purchase: today’s technology is Etnies STI Evolution Foam. Used in both the midsole and outsole of many of the brand's sneakers, this durable compound is designed to suit skaters better than traditional foams thanks to its high-rebound and abrasion resistant durability.

What is it? Etnies STI Evolution Foam is a compound used by the brand in place of traditional midsole and outsole makeups such as EVA, PU, and rubber. Designed with a molecular build that is denser than standard foams, Etnies STI Evolution Foam is able to more effectively stand up to the wear and tear of skateboarding. As an added bonus, Etnies STI Evolution Foam is made through molding process instead of being cut from a sheet, which means no waste is left behind.

How does it work? Thanks to its dense, lightweight construction, Etnies STI Evolution Foam offers the right amount of rebound for skaters, decreasing the likelihood of packing out. This also makes hard landings smooth and safe, so skaters will be able to go their hardest while remaining protected and cushioned.

Notable products: Etnies Marana

Bottom line: Skate sneakers need to withstand the rigors of rough landings and constant friction, and Etnies STI Evolution Foam is built to go all the way.
