This is an odd-looking contraption but it is fairly comfortable. I can easily wear it for about half the night in bed and can walk around the house a bit in it. I don't see how it could work with socks and shoes on. The button at the side is prominent. There are no instructions with it. It is easy to put on and tighten to fit but I couldn't work out how to take it off at first. Discovered that you have to pull the button outwards to release it, not turn it the opposite way.
