Forget business as usual. With its discreet black napa leather upper and 1½" pivot sole, this office-ready rendition of the muscle-maximizing MBT will let you sneak in your workout (and all the rest of those head-to-toe health benefits) whether you're standing at the fax machine, delivering a presentation, or catching the 7:20 train. Constructed with a curved last (for a specifically-femme foot), and MBT’s lowest pitch and longest sensor for maximum stability, simply pair them with trousers to tone 9 to 5.
• U.S. women's whole and half-sizes 6 1/2-11.
• The Black Shadow has a snug fit, so we suggest ordering a half size larger than usual.
