I love these wedges from H&M in green, although I'm not so keen on the cork style wedge. At £14.99 they really are a steal, and they come in white, black, light brown and pink too.
New Look Parallel Wedge in Yellow £19.99
These Topshop beauties are rather more expensive at £40.00, but I love the mint colour and they are 100 percent leather. The apricot and navy blue versions are also nice.
I also like the shape of this beige wedge from Urban Outfitters, and the elasticated slingback. These are £38.00 and also available in black, but I like the neutral beige as it could be worn with a multitude of summer outfits.
