Alex - most interesting and very predictable. In my area here near Cleveland, OH, Warren Grossman, PhD who is well-known as a healer often gives seminars and mini-talks on the value of using the athletic 'shoes' that are as close to going barefoot as possible yet are protective and acceptable for wearing out in public places.
Here, they are known as FiveFinger shoes. Several of the men at my fitness center wear (and love) them...there is only one woman that I've noted. I've been thinking of trying them myself.
Warren notes as you do that since they mimic nature, foot issues and balance problems disappear with time.
Most importantly, he notes, is that you get the 'grounding' effect when you wear them on natural surfaces such as soil and lawns so the benefits of collecting additional electrons to boost health is part of the process.
