Think of the ProPad SXS Support X-tra Soft Horse Shoe Pads as an arch support for horses. Made of the highest quality polyurethane material embedded inside to reduce concussion. Gives extra support to compliment the height of a shoe and acts as an extension of the frog, moving with the frog to promote healthy circulation of the foot and absorb shock. ProPads can be used in conjunction with any shoe brand. For horses in training, competitive or pleasure. Softer orange material embedded inside the heel, and all soft on the hoof side under the frog. Sold as pairs.
