"I bought these for work, and while they aren't non-slip, they have been comfy and held up pretty well. I have worn them 6 to 10 hours a day, 4 to 6 days a week so the cushions are not as forgiving as they once were, and now after 11 months of abuse there are rips in the rubber of the soles- but they have taken a beating and deserve their retirement! I will be purchasing a replacement pair with no qualms about it."
