Made from Hitemp, urine-resistant medical sheepskin, this thick-soled boot is suitable for indoor and outdoor use.

The flaps are held in place with adjustable Velcro fasteners. SIZES: Medium (shoe size 7-8), large (shoe size 9-10), extra large (shoe size 11-12), and extra extra large (shoe size 13-14).
