If you have a need for speed (13.5 mph worth) or are too lazy to walk around campus or your workplace, the iShoes will get you there without making you look too dorky in the attempt. The 123 Lithium-ion battery pack needs a two hour recharge for up to 3 miles of traveling. At a size of 11.8 x 19.0 x 4-inches, they weigh under 12 lbs. and can support up to 250 lbs. The iShoes come with a throttle cable and a MSRP of $499.00 (although the site lists a price of $599.99.)
