I ordered these for my husband who wears a size 17 and it is very hard to find boots for him that are dependable and comfortable for his line of work.  He says they are super comfortable!  I only gave the review four stars because I am not sure how long they are going to hold out.  I may increase it to five stars if these boots last longer than six months, which is the track record for every other type of boot I've ordered for him so far, no matter what the brand or the price.
