Inspired by the swirly shell of a large sea snail, the LeBron 21 'Queen Conch' is built for the basketball court. These low-top basketball shoes feature a synthetic upper with laces that feed through interior cables, offering midfoot lockdown whether you're a guard, forward, or center. Quilted textile lines a perforated tongue stamped with LeBron James' signature. For premium performance, these basketball shoes have a lightweight Cushlon midsole with Zoom Air technology. The Zoom Turbo unit in the forefoot and a large-volume Zoom Air unit in the heel provide a responsive feel, giving you the support you need to perform your best at an affordable price.
