If the original version is out of your budget, these MICHAEL Michael Kors Bromley boots are a great option for a little less cash. They retail for $198 but are only left in limited sizes at both Zappos (click on the photo below) and Michael Kors.
If the Michael Kors version is sold out in your size, check out this pair from Promiscuous. They retail for a bit less at $143 and you can click here to purchase.
Reader Janna just emailed me another great option from Steve Madden. They retail for $199.95 and you can click on the photo below if you're interested in purchasing.
