We've finally been able to ID the gladiators that Mary-Kate's been running around in for the last month! You can't get them anywhere yet because they're part of the forthcoming footwear collab between the Olsens' Elizabeth & James label and Steve Madden.

The "Edge" gladiator sandal is one style from the Pre-Fall 2009 shoe collection. The designs are strong but understated - their mutability in color and style make them adaptable for different outfits and seasons.

The collection will range in price from about $270-325, and is now available for pre-order at Nordstrom.com.
