I found these Sof Comfort Orthotic insoles at Walmart They were under $10.00 a pair which compared to some other insoles I have tried these work great and approximately 10-15 dollars cheaper in price. I experience very good stability, support and shock absorption in every step with these insoles. there very light weight and easy to install. There ready to come out of the package to fit a size 7-13 shoe, you just need to cut it to your size which is very easy to do. I have put these insoles in my running shoes, hunting boots, and also my Work boots that I sometimes wear for 12 or more hours a day. I have had no problems with my feet at all. I have been very impressed with the life of these also I have had these in my boots and shoes for nearly 8 months and there still going strong. I just bought a couple new pairs so I will replace them shortly.
