Some people have feet that are hard as nails. I don’t. Some people walk around without any shoes or socks on so often that the soles of their feet are like sandpaper. Mine aren’t. I have princess feet. If I walk barefoot on tarmac, or pebbles on the shore, or even sand sometimes, I wince. I need to put the work in to harden them up. But I’m worried it’s too late.
