I abuse my poor feet. If they were children they'd be whipped into care as the calluses, cracks and horrible old nail varnish don't suggest they come from a loving home.I've heard really good things about the Microplane foot file, which isn't available in the UK, and I'm wondering if the Ped Egg could be the British solution.
It's a foot file that's shaped like an egg, and designed to remove hard calluses and corns. Because it works at a high intensity you shouldn't use it more than once a fortnight. It costs £9.99 from JML, and I'm looking forward to getting sandal worthy soles this summer!
