LIGHTWEIGHT RESPONSE. The Mens Nike SB Portmore Vapor Skateboarding Shoe delivers the responsive flick of vulcanized construction without all the layers of heavy rubber. Its midsole mixes rubber with foam so it can double as an outsole, which sheds weight without sacrificing response. Midsole is injected with rubber to provide responsive flick with a lightweight feel. Suede vamp & heel offer durability. Midfoot gore straps provide a laced-in feel even if youre not. Minimal, slip-on-like fit offers a lightweight feel that wont weigh you down. Slim mesh tongue helps increase ventilation. Outsole has a herringbone pattern for excellent traction & boardfeel.
