In Sports World atm they have fantastic Karrimor walking shoes - trainer-styler, low tops - for £11.99 in sizes 3-6 (list price something mad like £50).
They have adult sizes too, for c £20 - can't remember exactly.
Really nice-looking shoes in beige or grey. Lots in stock at our store. (I might have bought some but I couldn't get the sodding box open to try them on - really weird box design! )
