The lengths I had to go to in order to try this, lol. I live in the suburbs, no open spaces around here to walk, but I wanted to give it a try. I live in GA, so walking on the pavement isn't really much of an option. Hot asphalt? So, I decided the only place I could really do this was at the gym, though I know I'd be kicked out for using the treadmill with nothing on my feet.
I settled for walking in my socks, and, though I wasn't exactly feeling the earth under my feet, it was different in a good way until I took a break at 45 minutes and noticed the soles of my feet hurt like crazy! I guess I'll need to build up some calluses, lol.
I had to put my shoes back on at that point, but that actually gave me the chance to judge the difference in the two. Barefoot walking does have a very different feel than wearing shoes which I found to be kind of pleasant. I'll see if I can build up my calluses and do more of this!
Your book club may have scintillating discussions. But my book club can drink your book club under the table.
