Inspired by the Feet You Wear concept from the 1990s, this colorway is an addition to the Boost You Wear collection. The Crazy BYW II 'Real Purple' features a Core Black mesh upper with a sock-like neoprene collar and a sheer TPU overlay. The sneaker also sports a Boost midsole with exaggerated arch support, Real Purple-hued accents throughout the upper, Three-Stripes branding under the mesh panels and a semi-translucent outsole.
