Have worn out multiple pairs of this particular shoe.  I do a lot of walking and workout on the treadmill, these shoes give good support and I notice that they seem to keep me healthier by giving me the proper support.  I am 69 and really appreciate a shoe that supports my whole body.  I can tell when it is time for a new pair when the body start to hurt.  When that happens I know its time for a new pair and that seems to solve the problem.
