About the Nike LeBron 21 Prime 96 'Fire Red'

The Nike LeBron 21 Prime 96 'Fire Red' draws inspiration from an OG colorway of Deion Sanders' Air DT Max '96 training shoe. Secured with an adjustable midfoot strap, the white leather upper features irregular cut-outs that reveal a textured crimson underlay. The two-tone design bleeds into the LeBron 21 midsole, featuring full-length Cushlon 2.0 cushioning with a springy Zoom Turbo bag in the forefoot and a bottom-loaded Zoom Air unit in the heel.
