I picked these up to wear over my shoes at work -- they've stood up to me on my feet all day, exposure to harsh chemicals (2k paint, lacquer thinner, gun wash, 99% isopropyl alcohol, etc.), walking around on a floor often covered in aluminum flake and pieces, acrylic and polycarbonate flake and pieces, indoors and outdoors (currently winter in Minnesota) -- for a few weeks and they're still going strong. No holes, no spots wearing through, not getting brittle or stressed from chemical exposure. I've been putting them on and taking them off frequently (I leave them at the shop but wear my shoes home).Color me impressed! I'm very happy with these and would recommend them. I was only expecting a few uses out of these based on other reviews and I can't say I've been gentle or careful with them.these are a very tight fit for a pair of 9 shoes. They don't last long on rough concrete surfacesVersatileGreat for when you need protection fasEasy comfortable greatRipped 3rd time putting them on. But kept feet dry while it lasted.Se rompen muy fácil, no es buena calidadArrived in no time! Apparently they will fit tou our feet and needs.Like-Good thoughtful productDislikeProduct developed little hole whilst stretching first time to slip on my shoe.in just 2 days,,,the product got tear apart.... please atleast provide some quality,,so we protect shoes till rainy seasonUsless product, it looks good to use but it tears out on using it. Mine got torn in second use itself. Worst product waste of money. If you're buying for rain protection buy a rubber shoes rather.Poor product quality - it ripped within 3 kms of wearing it.A very useful product
