Light up laces are cool and do work. They come with about 4 differrent light types straight glow, flashing, flicker and glow with the occasional blink. The only problem is if your shoe size is bigger then a 10 you probably won't be able to lace the plastic tube all the way up your shoe. They do go reasonably high enough so your shoe doesn't go flying off and the trade off of have cooler looking shoes is well worth it.
