I had a bunionectomy on my left foot that didn’t heal properly and as a result, I had to have a second round of surgery. All told, I was in casts and moon-boots for nearly ten months. When I finally rebelled against more treatment, I purchased a pair of MBT athletic shoes that have a convex sole. I purchased several pairs of these Superfeet green insoles from The Insole Store and started walking every day. I cannot express how happy I am with this product. It holds my foot firmly in the shoe and supports the arch comfortably. There are no blistering or other adverse effects and my regimen seems to be healing my foot whereas the prior immobilization didn’t. I can stand and walk for long periods in complete comfort. I would heartily recommend these insoles to anyone who has had foot surgery, especially those with a little wear on the treads.
