I got these from Amazon because of the price. She tried them on at Nordstroms and then I bought them through Amazon for Christmas. They look and work great with jeans/leggings, she has yet to slip with these on in my garage w/ oil all over the place. I have a pair, too, due to their non-slip and great quality. Mine I've had for three years and no issues, her? One year so far -- no scratches or scraped! Typical wear + tear!
