Yes, I did. But the reason I started using them was because I was getting hip pain from running and long walks, and the theory is that by using barefoot shoes your gait changes and you don't heel strike, and therefore the impact does not travel up the leg to the hips.
It worked for me. Quite quickly I stopped heel-striking (cuz it really hurts to do that in barefoot shoes) and the hip pain disappeared. However, I did get pain in other parts of the leg -- knees, tendons, etc. -- until I developed the foot strength and changed the mechanics up the leg and hips. That has taken a few years, but I persevered, and things are really good now. I run, hike, cycle, rock climb without any recurring body problems.
It took a long time, and I really had to be willing to evaluate and change my gait and work on strengthening the body parts that had atrophied after 50 years of life in civilization. It is not an easy transition to make, but I'm glad I did it.
