Barefooting is relatively easy these days because they have a fixed bar on the side of the ski boat that you hold onto and can support your weight as you set your feet on the water. From there, you start working with a very short line and keep extending it. I haven't acutally done this since my barefoot days was back when you stepped of a slalom ski, 75 feet behind the boat at 40 mph. I had more than my share of water blown into every orifice of my body, my balls busted and my head ripped off while learning to barefoot. I never did get very good at it and gave it up before long. That was 35 years ago and I am now older and wiser.
