I loved these shoes the first time I wore them 2 times. You are very bright! The third time, however, the charging port on the back of the left boot was missing. It fell off in the car because I was wearing it while driving. Then the port for the right boot fell off. I bought several pairs of LED and fiber optic shoes to wear while dancing and performing. I learned that when the charging port is on the back of the shoe, as is the case with this shoe design, it must be flipped to the side to charge. The wires are very thin and the stress caused by simply charging makes them prone to breakage. If you're considering buying shoes with LED lights or fiber optic cables, I recommend looking for ones that have charging ports closer to the shoe's tongue, where they're more protected and don't need to be twisted to charge. The 2 pairs I bought with the charging ports in this position lasted 4 and 6 months with regular wear while all other pairs (5) with the charging port on the back of the shoe as this shoe was designed broke. during the first pair of socks. Unfortunately they broke right after the 30 day guarantee but luckily Revain customer service was able to refund me for the broken shoes. Hope this helps someone! Buyers beware of this epic design flaw!
