Here's the Steve Madden version, which run about $150.
And here are a couple of alternatives that cost about half of that (and quite frankly, I can't tell the difference between these and the Steve Maddens):
Olsenboye "Indigo" boots from JC Penney: Regular price $70, on sale for $49.99 (+ free shipping)
Olsenboye is Mary Kate and Ashely Olsen's affordable brand that is sold exclusively at JC Penney. Even though those of us on the taller side can't really rock their dresses as anything more than a shirt, they have some awesome clothes that always seem to be on sale and JC Penney typically has some sort of coupons, too.
From what I can tell, these boots are only sold online and look a bit darker than the original Steve Madden ones. Personally I think paying $80 for boots from American Eagle is a bit too much but compared to the $150 for the Steve Maddens, it's a steal.
Happy Boot-hunting! How excited are you for fall? I'm dying to whip out some scarves and tights.
