Concepts x Free Trainer 1.0 'Thermal' Special Box Sample

The Nike Free Trainer 1.0 combines a zero mm offset for a barefoot feel with a lightweight rubber outsole that wraps up the edges of the foot for multi-surface grip. Massachusetts-based streetwear retailer Concepts teamed up with Nike for this ‘Thermal’ colorway of the silhouette to mark its 20th year in business. Inspired by sports science, the shoe features a multi-color thermal camera pattern on the mesh upper and a black thermal reactive tongue that changes color when heated. It also comes equipped with Flywire technology for a lockdown fit, a zero-drop foam midsole for stability when lifting weights, and a specially designed custom box.
