How about magnetic levitation shoes?
I'm wearing YAMORI maglev sneakers. They pay attention to health and are very friendly to pregnant women and the elderly. The innovative design of "spring+magnet" is adopted in the sole, which can not only effectively reduce the damage to human feet and knees caused by seismic waves caused by exercise, but also solve the problems of dampness and foot odor caused by traditional shoe ornaments because of its characteristics of air floating up and down and natural exhaust, so that it is comfortable and healthy to walk.
