Steve Madden's 'Kasidy' t-strap wedge sandal is a great take on the gladiator trend. Get them in black, brown, purple or metallic for $79.95 at endless.com.
Mossimo's 'Pollyann' woven wedge sandals look nearly identical to the Steve Maddens but cost a lot less. I tried these on in person and they look fab, if I hadn't just purchased two pairs of Cynthia Vincent for Target sandals, I would have bought these too! Pick them up in black or brown for $22.99 at target.com.
