I think it’s all on the persons lifestyle and making better choices. If you have the option to be barefoot (home, in the car, etc) make that choice. Barefoot all the time can be taxing if you’re not just lounging around all day. Not to say it’s bad, but you gotta work up to it. I’ve seen Kelly in many different shoes. He even talks about vivobarefoot shoes (he wore them on his creative live interview I believe). Bottom line, make better choices. Thicker shoes will shorten your heel cord over time and dull your nerves at the bottom of your foot. Also, check out shoe cue inserts. I haven’t used them yet, but I believe they could be beneficial with improving foot mechanics.
