I have arthritis in my hips and knees. I am on my feet, all day, every day working for Fred Meyer. I walk many miles, on hard floors and, it was getting so I could hardly walk at the end of the day. At the end of the week, I was ready to die. I purchased these boots on the first day of a vacation and, decided I'd wear them during the vacation to break them in, so I wouldn't have to go through the "new shoe pain" at work. Well, there was never any painful breakin period. The boots felt fantastic from the start. Now, my hips and knees don't hurt at work. At all! These boots have made a terrific difference in my quality of life. I went out today, and purchased another pair, so I can switch them out so they'll last longer, and get to air out. I can't say enough good things about these boots and, can't think of a thing negative to say, either. I, honestly, may purchase a third pair just for the heck of it.
