Unknown total mileage, but in excellent used condition and still feel great. I did one 3.5 mile run in them, but since I like more rockered running shoes I've just been using them for casual use.

No rips, tears, or stains on the upper. More pics here: https://supwell.circle.so/c/shoe-marketplace/asics-kayano-31-12m-65-shipped-to-uscon
