Launched in 1991, the Disc was the first lace less sports shoe with a system of internal wires that tighten the upper for a perfect fit. We revamped the model in 1993 and kitted it out with our signature Trinomic performance running tech, and we called the shoe the Disc Blaze. Now, it's back. The Never Worn version features a mix of retro materials and some beat-up elements like glue stains and abrasions for a truly old-school look.
