Isabel Marant's Forbes suede booties are a favorite of Kate Bosworth, and were also recently spotted on Kate Hudson. I was unable to find them in stock anywhere online, so unfortunately I don't know the exact retail price of these shoes. (Photo credit)
If you love the look of the Isabel Marant version, check out this boot by Kimchi and Blue. They retail for $58 and also come in grey or red. Click on the photo below to purchase.
*Update - 8/4/11* - This post is originally from April 2010, so the Kimchi Blue booties are long gone. However, I recently spotted another alternative from Old Navy. They come in brown or grey (shown) and retail for $34.94. Click on the photo below to purchase!
