DD1-16 has started sixth form and needs some new shoes for school. Dress code is business dress. She has small feet, size 4 at best, and wants some black Chelsea boots with a little elastic at side and low to medium heel. We have looked in quite a few shops but she hasn't found the ones she wants yet, especially in her size. She walks a mile each way to school so comfort and durability are musts.
Any suggestions?
