I do both and let me say that anyone can board. I have tried to teach several people over the years to barefoot (mostly without a boom) and footing can kick the crap out of you. That why I like boarding. Much easier on the body. Not always, but most of the time.
Whatever guys..... I learned how to barefoot and ski way before I learned to wakeboard. I havn't footed in a few years, but I bet I still could. Digging a toe at 40 is nothing like getting lit up hooking an edge backward landing out in the flats. When you dig a toe you don't have anything attached to you to make you stop....instantly, like a board does. Anyway, for what its worth, I doubt I'll ever foot or ski again.
