Adidas Skateboarding 3ST.004 Boost Triple Black MSRP $120 Gently worn with tons of life left. Super comfy Boost sole. Built with insights from the team at adidas Skateboarding, the 3ST.004 sneakers were designed with a Boost midsole for energised cushioning and a moulded heel clip for added stability - helping the skateboarders get better performance. The fourth installment in the line, the Adidas 3ST.004 is designed purely for skateboarding. The BOOST™ foam in the midsole offers reliable and responsive cushioning, and the cupsole construction makes them stable and supportive. A single piece toebox keeps all of the rip-able seams back away from the highest wear areas and the breathable mesh tongue is connected to the midsole giving you a secure and snug fit. On the outsole is the Geoflex tread pattern that gives the shoe extra flexibility and multi-directional grip.
