Attended to purchase a pair of walking shoes and a pair of walking boot. Not fitted correctly as they were both too small, though they felt fine inshore. The attendant did not know how to advise on shoe fitting. The walking shoes caused toe and nail bruising on first walk. Returned to store on two occasions. On the first occasion there was only a manager at the store and he could not assist. On the second occasion a manager fitted walking shoes one size larger, noting that the used pair was too small such they my foot completely covered the length of the extracted insole. As the walking shoes had been used they could not be returned. The walking boots however were returned.
