Are your Tiger Paw Wrist Supports getting a little soft? New foam inserts will stiffen your Tiger Paws up again. The foam inserts in your Tiger Paws were designed to be replaced so you can continue to get solid, stable support without having to purchase a new pair of Tiger Paws. The foam inserts generally need to be replaced after about 30-45 hours of use. Be sure to order your replacement foam inserts in the same size as your current pair of Tiger Paws. Sold in pairs.
