These shoes have plenty of life left in them! I think I only put about 30 miles on them and any wear is only cosmetic (Some black on the inside of the sole is scraped away from my feet rubbing against each other, shown in pics...cosmetic only. Also shown in pics, on the inside top near the tongue there is some darker ink transfer from socks.) I loved these shoes but haven't been able to wear them since a bad bout of Plantar Fasciitis :(
