Care Instructions: VELOUS shoes can be wiped clean with a wet washcloth or washed off with water. They are also machine washable at cold temperatures on the delicate cycle with other clothing items. To maintain the intended support, flexibility, and fit of our proprietary technology, keep your VELOUS shoes away from extreme heat; do not put VELOUS shoes in the dryer, or leave them exposed for long periods of time to the hot sun. VELOUS began with a question: Why can't recovery footwear provide both cushioning AND support? Three industry veterans sought a recovery footwear solution that offered the ultimate combination of stability, support and cushioning. VELOUS Footwear's 'Tri-Motion' sole was born, providing what the foot needs in each area to help athletes of all levels properly recover.
