!Hello. Im trying to lodge a complaint in your defective CONTACT US section.. But the "+ Photos" link is not working and I cant upload photos.!!!! These black US5 LED shoes would only flash occasionally when worn and if yu pressed the buttons manually it wouldn't always go off. We put new batteries in them and it made no difference. The left one actually stopped working all together. And also they are a VERY SMALL 5US. they are more like your other US4 shoes. ? What would you want to do. I am a very regular customer and I haven't had any problems with anything till now. . Could yu send me a replacement in 6US maybe?? User's recommendation: Contact via Facebook messenger.
