I bought DD some boots from MandCo. We don't have much choice in out town.
She has had them 5 weeks and they are unwearable, so I returned them.
The shop did exchange them but said they wouldn't do it again as they are a clothes shop and only sell shoes and boots as 'fashion' accessories 
and therefore are not obligated to exchange or refund as they are not meant for general wear.
There are no signs in the shop (or none obvious enough to make it clear).
I sort of concurred politely but was actually thinking that it sounds like a big load of bollocks. Well, that bit might be U of me but I have a headache.
The young girl was very lovely about it all and I presume only spouting relaying shop policy.
