One thing I noticed about going barefoot is that although my feet haven't gotten bigger my arches seem to have gotten stronger.

I used to wear full length orthotics supposedly to help knee problems. After a PT told me I didn't need them and I was reading about the barefoot movement I eased myself off the orthotics and went back to going barefoot. To take up some volume in my cycling shoes I got E-Soles with various arch heights.

At first the lowest arch felt too high and uncomfortable, especially when standing or walking in my bicycle shoes. Odd because I have a pretty good arch. This year I noticed that I didn't feel the arch support at all. Thinking the original support was just broken down I put new ones in. Amazingly, the new ones are the next to the highest level provided by E-soles. Unlike when I first started using E-Soles I hardly notice the arch support. I tried changing the metatarsel pads but my feet didn't like that at so I went back to using the old ones.

The only thing I can figure out is that having the arch support of the orthotics for so many years weakened my arches. I'm sold on being barefoot as much as I can.
