I've put 100 miles on these shoes this month. What a difference !  I have a new puppy ( 5 months as of this review ) the first month we had her I was walking her in Crocs or my work boots. Nothing but back and shin problems. Since getting these shoes my pain problems have went away and I've even increased my monthly total by 30 miles from June to July.  Edit ( December 2015 )   They only lasted about 3 months.  I did a fair amount of walking in that time, but I wear a pair of work boots for roughly a year at a time w/o a problem. The insoles tore, and I started having leg & lower back pain. Bought new shoes for dog walking and pain went away.
