The Nike Free Trainer 1.0, which provides a barefoot feel thanks to its zero mm offset, offers excellent traction on various surfaces with its lightweight rubber outsole that extends up the edges of the foot. To commemorate Concepts' 20th anniversary, the Massachusetts-based streetwear retailer collaborated with Nike to create the 'Thermal' version of this silhouette. Taking inspiration from sports science, the shoe boasts a visually stunning multi-color thermal camera pattern on its mesh upper, while the black thermal reactive tongue changes color when exposed to heat. Additionally, the shoe incorporates Flywire technology to ensure a secure fit, a zero-drop foam midsole for stability during weightlifting sessions, and comes complete with its own uniquely designed customized box.
