The Wall Street Journal reports that Ducere, a company in India, has come up with a new entry in the "wearable technology" field: the Lechal smart shoe, aka "interactive haptic footwear". The shoes are bluetooth-enabled so that they can communicate with Google maps and guide your feet on their way to where you want to go. When you are at a crossroads the left or right shoe will buzz to indicate which way to turn. Insoles for shoes will also be available if you don't want to wear their shoes. I can't find an estimated date of when they will be on sale, but the story does say that the shoes should cost between $100 and $150 which admittedly isn't super cheap but is a lot less than some shoes cost.
