Nike re-engineered these Zoom Dunks with a Flyknit constructed cuff that offers optimized lock down and added support that moves with you as you skate. This cuff technology was originally developed for soccer players who wanted a super snug and lightweight fit at the ankle that felt more like a sock than a cuff, and was able to provide a more stable feeling experience. Good for soccer but also great for skating, once again Nike has adapted their advanced shoe technology to aid skateboarders and the result is wonderful.
Cupsole - Cupsoles are durable, well-cushioned and provide the best impact protection against hard landings. The sole consists of a single rubber layer, reinforced with glue then stitched to the upper. Cupsoles generally last longer than vulcanized soles, but don't provide as much flexibility and board feel right out of the box.
Nike Free in Forefoot - This technology promotes natural motion in the forefoot for the ultimate in comfort and flexibility.
Flyknit Cuff - Flyknit Cuff construction provides a featherweight, formfitting and virtually seamless upper. This unprecedented precision maximizes performance with the snug (and virtually unnoticed) fit of a sock.
Nike embarked on a four-year mission with teams of programmers, engineers and designers to create the technology needed to make the knit upper with static properties for structure and durability. Then the precise placement of support, flexibility and breathability—all in one layer—was refined.
EVA Foam Sockliner - Ethyl Vinyl Acetate (EVA) insoles are a firmer material than you would find on standard orthotic insoles to offer better shock absorption while reducing the weight of the overall shoe.
Visible Zoom Air Unit - Provides low-profile responsive cushioning
