I do a lot of walking and, unfortunately, much of the walking is on cement. Sometime long walks would leave my feet feeling fatigued and a lot of discomfort. I wasn’t sure if these Max Cork Insoles were going to work much better than the regular ones that came with my shoes but I was willing to give it a try. To my surprise, they worked perfectly. I’m not feeling the discomfort I felt before. Now I automatically add them to the cart everytime I buy a new pair of shoes. They do make the difference.
