We have covered a bunch of cool, smart shoes here in the past. X-Shoe is a motorized shoe that lets you travel at a top speed of 15 km/h. Of course, you can lock its 4 rubber tires to walk when you need to.
The ESMAR X-shoe has a battery with a range of 5km. Users can start or stop the shoes quickly. The structure is waterproof. These ship in October.
