What is Returning running shoes after they have been worn?

A worn returns policy tells you whether a brand takes back shoes once you have run in them. Indoor try-ons are one thing, but sweat, scuffed outsoles and a settled midsole sit outside most standard windows. Altra is the exception in this group and accepts worn returns, while BeLenka Europe, Decathlon, Merrell and Mizuno all say no. Practical effect: once the mileage is on them, a refund is gone and you are shopping at resale value instead. Ask before a long run in a new pair, not after.
