Tiger Paws getting a little soft? These foam inserts will make your Tiger Paws feel like new again. The foam inserts in your Tiger Paws were designed to be replaced so you can continue to get solid stable support from your Tiger Paws. Foam inserts generally need to be replaced after 30-45 hours of use. Please order replacement foam inserts in the same size as your current pair of Tiger Paws. Sold in pairs.
