Very comfortable. I usually wear a size 13 but only had a size 12 in stock. They turned out to fit very well. Sturdy enough to use tools with shovels and the like. I only wore them without socks. They tend to make fart noises but may not be wearing socks. I haven't seen them roll around my foot on hills or slopes at all. I only wear them in the early morning or in the rain when it's cooler. So I have no idea if they get too hot in warmer conditions. They're black, but if you look closely you can see the leopard print on them, but it's barely noticeable. I weigh 290 pounds. If poorly constructed they may not last me very long and I will update the review. At the moment I am very happy with them.
