The adidas UltraBoost 22 Cold.RDY running shoes are the perfect choice for winter running. The upper is insulated for warmth and comfort in low temperatures, while the grippy Continental™ Wintergrip™ Rubber outsole provides secure footing on slippery streets. Energy-returning Boost and a Linear Energy Push system keep you going longer. The ‘Black Grey’ color scheme applies a stealthy look to a running shoe designed for chilly weather. Made with at least 50% recycled content, the black textile knit upper is insulated for warmth and bolstered with tonal no-sew overlays. The lightweight build sits atop a full-length Boost midsole, with responsive cushioning properties enhanced by adidas’ Linear Energy Push system. Underfoot, the lugged outsole made with Continental Wintergrip Rubber ensures improved traction on slippery surfaces.
