Create your own custom-made shoes, slippers, or espadrilles with the Opry Soles! The soft and flexibles soles are made from viscoelastic polymer and consists of two layers. The sole has practical holes around the edges of the top layer where your fabric, crocheted or knitted work can be sewn on. The holes do not pass through the bottom of the sole, so the underside of the soles are smooth and comfortable for walking. Each pack contains a pair of soles.
