On Cloudstratus Lake Flare Men's 10 with original box “The Cloudstratus is designed for maximum cushioning. It’s made with the company’s light, bouncy Helion foam integrated into two rows of CloudTec units stacked on top of each other, creating a smooth ride while preserving responsiveness and saving on weight. The asymmetrical upper is made from a flexible, breathable mesh, and combined with the star lacing system, it should deliver a snug wrap around your foot—although it’s designed to accommodate wider feet.” Runner’s World
