Concepts x Free Trainer 1.0 'Thermal'

The Nike Free Trainer 1.0 combines a zero millimeter offset designed for a barefoot feel with a lightweight rubber outsole that wraps up the edges of the foot for grip. Massachusetts-based streetwear retailer Concepts teamed up with Nike for this ‘Thermal’ colorway of the silhouette to mark the company’s 20th year in business. Inspired by sports science, the shoe features a multicolor thermal camera pattern on the mesh upper and a black thermal reactive tongue that changes color with heat.
