I purchased shoes for my 4 year old that light up a few months ago. Within a month two of the lights went out on his illuminator sketchers and of course I could not find the receipt (although I have a receipt for everything else I have purchased in the last 5 years). Since these shoes were rather expensive I was not a happy camper.
A few weeks ago a woman told me that Famous Footwear is great about returns even without a receipt. I crossed my fingers and took his shoes in to exchange them for a new pair. I was pleasantly surprised when they exchanged the shoes for me without a fuss or dirty look. I really appreciated the understanding given to my situation and the smooth process of exchanging the defective shoes.
