Saucony Ride 15 Runshield Frost Running Shoes White Mountaineering and Saucony’s latest collaborative sneaker: the Grid Web. The construction remains 10k from the OG, including the GRID cushioning in the heel, but it's the bold styles of the era that take centre stage here, influencing both the vibrant accents and the model’s signature cage-like overlays. In fact, the only thing that isn’t bold or retro is the White Mountaineering branding at the heel.
