My feet get tough and calloused in the summer when I walk barefoot on the pool deck.
My feet used to get like that as well in the summer, because I liked to go barefoot whenever I could. Even going out with friends, I remember one time one of the other girls with us managed to break the heel off one of her shoes, so as we had the same size of foot I lent her my shoes and walked barefoot along a dirt track.!!
