These shoes are powered by an electric motor coupled with a battery. They will get you going a good 15mph at top speed too.
The only two downsides so far is the fact that they are still in development, and the fact that they will only last for about 7-11 miles. They have 4-inch wheels and strap onto your feet like the old school metal skates used to.
The 4-inch wheels make them more stable, and also make them usable in more types of terrain. They weigh 16 pounds, come in sizes 8-12 men’s or 7-11 women’s, and have a cable that controls thrust and braking.
