Query: doesn't work well without shoes

Maybe it's just me, but I found this next to useless if you aren't wearing shoes. As you can tell from the picture, the footbar can be secured in one of three positions over your feet. However if you're in bare feet or don't wear your shoes indoor like in my house, I found that even the lowest setting is still too "high," meaning it is still too far away from the door/floor and doesn't hold your feet down firmly at all. I tried using it a few times and have gone back to just sticking my toes under the couch.
