Okay, so we're total gym-phobes. And when we do make it onto the treadmill - well, let's just say our focus is more on the hard body glistening on the machine next to us than on the calories we're attempting to burn. Hence our obsession with the FitFlop ($45), a sandal made with patent-pending "microwobbleboard technology" that keeps the foot destabilized, forcing muscles to work harder to keep us upright. Thighs, calves, and glutes get some serious toning; and the sandals also have been proven to burn calories, reduce cellulite, and improve posture. The flops, which originally launched in London to overwhelming success, have already sold out in the US, but you can pre-order a pair on www.bathandbodyworks.com. Also, a new shipment is arriving at Bath & Body Works (CambridgeSide Galleria, 100 CambridgeSide Place, Cambridge, 617.494.8066) in mid August. They come in red and black styles. Even Pamela Anderson has been spotted wearing them - and we all know she's got great gams to go with her other excellent, er, attributes.
