The Nike Vapor Court was created for the tennis player that values a lightweight design and prefers a natural motion ride. This shoe features a split leather upper for a supple fit and feel and synthetic leather in the higher wear areas for added durability. The midsole was designed with natural motion principles for a greater range of foot motion. Unit sole foam in the midsole offers lightweight durability, so you can be quick and you're shoe won't break down. There's Nike GDR rubber in the areas of highest wear on the outsole for long-lasting durability. Wt. 10.2 oz.
