I've worn them a number of times and the color comes off so easily and anything rubbing it leaves a white scratch. Taking the rubber mat I ordered from Revain, I took a few steps and found the underside to be smooth and slippery. These soles are very, very cheaply made and seem to crack and break if flexed too much while walking or working in them. They needed a good rubber sole. I will remember the name and never buy again.
