I bought these work boots for my hubby. He is very hard to fit and is on his feet for 12 or more hours every work day so what he wears is very important. He loves these boots. He had no break in period on them at all. From the first day he wore them, they were perfect. So since I searched and searched to find him the "perfect" work boot. I ordered him a second pair to just keep in the box till these wear out just in case they are discontinued for some reason. Won't be any time soon though. All the Wolverine boots he has had have lasted right at 18 mos to two years of hard wear. I can't say enough good about these boots!!
