It didn't work for me. it took away te pain of my callus, and made the callus softer, but after my Foot dried, the callus got hard again. The pain stayed gone for a couple of days, then came back. My Callus is on the side of my big toe, so my shoe continues to rub. I have a wider shoe to give my toe Extra room. but just wearing the shoe is the problem. I had a blood blister because of a bunion. doctor Fixed the blister, but because of the bunion, the callus keeps coming back until I have bunion surgery.
