Sheik is an "urban teen" brand that specializes in things like Baby Phat and rainbow skull cargo shorts. Not the place you might expect to find a killer pair of shoes.
I picked up a pair of these "Segment Wedges" at a shop in Berkeley. So far, they've turned out to be one of my most comfortable and durable favorites. The heels have barely worn at all after a couple months of my city walking. And at only $40 with free shipping, they're not too hard on the wallet either.
