I get about two (almost 3) years out of my shoes so this looks like maybe 3-6 months of life out of them. I think they are in great shape. Since they don't make them anymore, I think this is a great deal. I will do a quick cleaning using chlorine dioxide on them and voila deodorized and disinfected all in one. Thanks for having these and thanks for the coupon, but I am good here.
