A collaboration with Dwayne 'The Rock' Johnston, the Under Armour Project Rock 1 'Black' features a fully knit upper for a compression-like fit that stays breathable, plus a synthetic overlay for added support. An adjustable lacing system, forefoot webbing and TPU heel counter combine to provide support and stability, while the one-piece Micro G midsole offers energy return with every step. Underneath, a rubber outsole has a unique knobbed traction pattern that allows for extra grip.
