I’ve tried recovery boots in other brands but decided to purchase these in the pants design to include glutes and hips. I’ve very happy with the design and the effectiveness. The pressure is great, much higher compression than other brands. The controller is easy to use. The cords are very difficult to remove once connected, so I have been leaving everything permanently connected.
I’m 162cm tall and 52kg and the smallest size option is a medium but works fine (although very roomy when first worn, the pressure does close in the spare space). At my height, I can't use these pants sitting up due to the pressure on abdominal contents restricting diaphragm movement (ie it's too hard to breathe), but lying fairly flat and keeping the top of the pants fairly fitted before inflation helps reduce the breathing restriction. For size comparison, my husband is 183cm tall and 78 kg and he can almost fit into the medium (tight at the hips for him) but obviously the large would be the ideal size for him. Unfortunately the bonus gift that was supposed to come (along with the purchase) never arrived.
