If a runner has poor running form and is concerned about injuries from running, electric wheelchairs may cushion and protect the runner from impact forces, as well as stepping on sharp things.

Electric wheelchairs prevent overpronation, and oversupination.
Given this information, shouldn't everyone be racing in electric wheelchairs.
Did I say electric wheelchairs? I meant modern running shoes.
