Technologies

Who knew charcoal bamboo could create something that keeps your feet warm? But it makes KEEN.Warm—a lightweight insulation that provides warmth where you need it most.

Care

Gently brush the footwear with a soft bristle brush or hand towel to remove loose dirt and debris. Stains can be treated by lightly rubbing a gum eraser in a circular motion over the location and lightly brushing afterwards. Tough stains can be treated with a mixture of water and a little vinegar on a damp cloth. This process may cause slight discoloration to the area.
