Keen Yogui Walking Sandals Lightweight and breathable, the Keen Yogui Walking Sandals allow cool air to circulate, keeping your feet dry and comfortable as you walk. A non-marking rubber outsole delivers optimal grip and traction without scuffing or damaging indoor surfaces. Injection Moulded EVA Upper Injection moulded EVA resides in the upper of the Yogui Walking Sandal to provide optimal comfort and responsiveness. The EVA improves cushioning and comfort, helping to lessen the impact placed on your knees and joints while you walk. A textured footbed reinforces the upper whilst the open nature of the sandal encourages cool air to circulate, creating a drier, healthier environment for your feet to thrive.

The outsole offers a firm, assured footing over varying terrain, enabling you to walk with confidence. In addition, the rubber provides flexibility to increase your range of motion. You can wear these sandals indoors without the worry of scuffing or damaging your indoor surfaces.
