We really don’t know that the sneakers with LED lights are the rage now. Fortunately the fashion sneakers can be customized by ourselves, for instance, the following sneakers.
From the images, apparently the prototype of the custom sneakers are a pair of Cseatme Secseation sneakers. The creator Creative Recreation added numerous LED lights on the surfaces of the sneakers. The LED sneakers look really shiny, and it can illuminate your road in the dark, but the black cable seems a bit redundant. No doubt, a replaceable battery will be much more better.
By the way, as a huge Iron Man fan, you might like to check the Iron Man and War Machine themed sneakers, of course, both of them have arc reactors.
