New! We've found this new shoe from Muck to be perfect when taking the dog out for a quick run or to check on the kennel at night. These boots are 100% waterproof, lightweight and flexible. The full-perimeter outsole and cushioned EVA midsole provides maximum protection to the toe, arch and heel areas. These boots have a breathable Airmesh lining to prevent overheating, keeping feet dry and comfortable. The unique cinch lace lets you slip the shoe on and with on quick tug on the cordlock, they're snug and ready to go.
