I have a severe lack of arch support, with a massive inward roll. It hurt to walk and stand. While I have shoes with arch supports in them, the choice is limited. The Physix Gear Orthotic Inserts with Arch Support, have surprisingly provided me with support like the specialised shoes I have without the massive cost.. It’s been two weeks now and I am amazed at the difference I feel and that my limping has also improved. I purchased these as a result of a friend who raved about them as well.
