Going bare-foot, wearing sandles and such and never sanding and putting lotion on your feet will definately cause them to look terrible when they are so dry, calloused and cracked.
I find if I just use a very abrasive emery board (the Ped-Egg will also be fine) once a week, then put Jergens Ultra Healing Lotions and then socks, either during the day or wear the socks to bed, your feet will stay nice and soft.
