I thought I had posted about the various Isabel Marant lookalikes but I guess I never did! Thanks to Julie for sending me the Bamboo by Journee find!
Isabel Marant's Otway bootie retailed for $1295 but is not available online.

If you love the look of the Isabel Marant version but don't have the extra cash,
Bamboo by Journee has a great alternative for $39.99. They come in grey, red, or black and you can click on the photo below if you're interested in purchasing.
Alloy also has a version for $42.90, which comes in both black and grey. Click on the photo below for more information.
