All you have to do is plug the usb into the charger box and wait until it’s fully charged

The batteries are easily removable and quite quick to charge see the photo they have dual microusb chargers i would reccomend wearing a thin sock under them as the washing process is delicate and you most likely dont want to be washing them very often

Changing the mode is as simple as tapping the button on the batteries long pressing the button will turn them on and off

After putting them on its definitely noticeable your not wearing a regular old sock

After i charged up the batteries i went in for the kill to see what the hype was all about and turned them on
