Hi everyone. I used to do PE about 8 years ago and kinda stopped. The only thing that I could use pain free was a silicone stretcher that attached below my knee and I could wear it all day under my clothes. I had someone send me a link on here to his eBay store that sold them. I cannot find the device at home or on eBay. Does this ring a bell? Does anyone know who that it or it they still sell a product like that. Thank you for any input.
