The Vans Colour Theory Collection features unisex footwear and apparel inspired by gender fluidity. A low profile slip-on shoe, the Vans Colour Theory Checkerboard Classic Slip-On has elastic side accents and padded collars for extra comfort. It also features the Vans flag label and signature waffle outsoles for firmer grip. The materials used in the manufacturing of these styles (including adhesives) are free of any animal by-products and therefore are 100% vegan.
