I suffer with dry cracked skin on my feet, it's worse after summer what with flip-flops and going barefoot a lot !!!
I have a pair of those loofah type mitts that you use in the shower, so I scrub my feet with those using a little soap, then dry, loads of intensive 24 hour hydrating body lotion stuff, pop some socks on, and here's the really glamorous tip, wear them overnight !!!! So sexy, not !! but it's working and I'm only having to do it once or twice a week and seeing good results!!!
