I was looking for a step with an aggressive tread; and I found these; and I'm very pleased. In my case they slide on easily. They're comfortable; and look good. And I'm very happy with the lugs on the tread; I'm sure these will do well this winter. The quality of the build is good too. My only complaint was that the manufacturer didn't seem to have made enough black versions of this shoe. I wanted black but I liked the look of the shoe, and the tread pattern so well; I opted to get the brown ones when I couldn't get the black ones I wanted. I will buy this brand again.
