They fit my son well. He wears a size 7 in mens. Nice and think. Bright colors. Good quality and look awesome!

Batteries come with some sort of charger. I charge one and it lasts longer than the batteries they sent. Comes with a dual usb>micro usb so you can charge both batteries off of one usb port.

Vif you need a rechargeable battery for high end components this is not for you. Less duration than a normal 9 volt battery. Dead on arrival.
