The Asda website describes these as "wedges", but that looks more like a small heel to me. Either way, these would be a really useful shoe to add to your summer wardrobe, as they're low enough to be comfortable, but with that small heel/wedge to help give your foot a bit of support. The silver colour means that you'll be able to wear them with just about anything and, best of all, they're only £7, which makes them a bargain indeed!
