These boots from Aldo are leather and retail for a reasonable $160. They have a buckle, which the Loeffler Randall version doesn't have, but I kind of like it for an extra little detail. They also come in black or cognac and you can click on the photo below to purchase. I might have to consider these for myself...
Steve Madden's Intyce is also an alternative, retailing for $148.95 (comes in several colors). Click on the photo for more information.
Go Jane also has an option in cognac or black for $30.80 - click HERE to purchase.
And finally, if you don't like the buckle and want something closer to the Loeffler Randall original - Nordstrom has a great option in cognac or black which retails for $119.95. Click on the photo below to purchase.
