Throwback track style, subtle branding and modern materials. With a classic fit and cut, bold branding, and updated with recycled materials, the adidas Skateboarding SST Track Pants continue to be a skateboarding staple. These pants were made using UNITEFIT — an all-gender fit system that was created with a spectrum of sizes, genders and forms in mind. Made with a series of recycled materials, and at least 70% recycled content, this product represents just one of our solutions to help end plastic waste.
