This post is literally years old.... But whatever I'll say it anyways. I use Official Sole Savers on all of my shoes and I love it. Love the product and love that the guys behind it are honest and aren't trying to scam or get one over on anyone. I had them on electrolime Foamposites, wore for about 4 months ALMOST EVERY DAY, wore them IN THE WOODS, and when I peeled them off the soles looked DS. The residue on foams is way to get off, but yes, it's annoying on other shoes and takes practice to get rid of. I highly recommend it. If for some reason they're defective or fall off during your first wear they'll send another pair out your way. (Keep in mind applying it well takes much practice.) I highly recommend these if you're anal about protecting your soles.
