These are very comfortable. I normally wear a size 13, but only a 12 was available. It worked out these fit very well.
 Durable enough to use tools with shovels and the like.
 I have only wore them without socks. They do tend to make a fart noise, but maybe they would not with socks.
 I have not experienced them rolling around my foot at all on hills or slopes.
 I have only wore them in the early morning or rain when it is cooler. So I have no idea if they will be too hot in warmer situations.
 They are black but if looked at closely you will see a leopard print to them, but barely noticeable.
  I do weigh 290 lbs. If they are not well constructed they may not last me very long and I will update the review. As for now I am very satisfied with these.
