I can kill a pair of chucks in a month but I had 1 pair of these boots for 3 and 1/2 years of daily wear and pairs of soles. Just bought another pair to replace them. What did them in was a 75lb wieght from knee high. I Ride a 02 vfr and a 91 gsxr and would recommend them to anyone looking for a mc boot they can walk in.
