iShoes might look a bit odd but for a concept they are thought provoking, at the least. An invention designed by brothers Ilya and Boris Kaganovich from Minnesota, the iShoes will carry you along at up to 15 miles per hour.
These shoes are motorized and controlled with a hand unit, so that you can pace yourself on short trips. Unfortunately, they only go about five to seven miles per charge, but for a quick shopping day (if you don't mind looking a bit odd) you could utilize these most anywhere.
No pricing out on them yet, as they are a prototype, but I would expect others to grasp the idea and come up with some more advanced ideas so that adults can skate around town like the kids do. They are like adult Heelys, right?
