Keen Women Whisper Sandals (8, black) - Pull on the KEEN Women's Whisper Sandal before you take on the white caps at the Royal Gouge. Keen gave this sandal a heel strap and quickdraw elastic cord to ensure you don't lose your sandals when you step into rushing water. The polyester webbing with antimicrobial treatment prevents your feet from smelling like a river bed when you're back at camp, and KEEN's patented toe protection prevents underwater debris from slowing you down. The EVA footbed keeps your dogs comfortable for the long haul, and the grippy rubber sole helps you stay upright on slippery surfaces.
