Wondering what others think: when Stand Up Paddling on moving water, a major concern is that when you fall off the board, your legs can go pretty deep, so you should always try to fall flat so as not to entrap your feet. This Leg Floatation Device (LFD) might help with this, or at least, that's what it's made for...

Is the idea any good in practice or only in theory?

What do you guys think?
