Me neither (too lazy for that), but I know they are used and abused by people too. This leads to funny cases I heard of like a company specifying that some shoes are for "walking", not for "running", and refusing to refund them if you admit to running in them.
If it's "not unreasonable" for them to reject warranty claims if you run in shoes "not intended for running", does that mean it is reasonable to make a warranty claim on shoes "intended for fashion" if you're not picked up while wearing them?
"Wore these heels to six bars, didn't get hit on once. Please repair or refund."
