The sporty Barett sandals masquerade as super-cute footwear, but they're really a fitness phenom. The secret's in the sole -- an embedded smartchip counts every step you take and tracks it on your smartphone. So all you have to do is walk (comfortably) toward your fitness goals (with nothing more to strap on). From TRAQ by Alegria. Knit upper Padded insole, textured outsole Bluetooth wireless technology for use with TRAQ app; compatible with most iOS and Android devices Approximately 1" heel Fit: true to size Fabric upper; man-made balance I have not tested the smartchip as I do not have a compatible device to test.
