The Pro H40 Tall Skid Boot was designed with the reiner in mind. Using orthopedic grade neoprene, cut to fit snugly just above the hoof, you get a boot that really keeps the dirt out. The exclusive PRO V tabs make application a breeze while the matched hook and loop surfaces mean this boot won’t wear out prematurely. Burn protection is provided by an extra thick rubberized patch which is flexible enough to conform to the leg without any hard points that might irritate. Machine washable. Available in small, medium, and large Boot Sizing: Measure around leg halfway between the knee and fetlock: Under 7" = Small 7" to 8" = Medium 8" to 9" = Large 9" to 10"= XLarge
