If you spend a lot of time in the water or on the beach, or just lounge around a lot with no shoes on, you’ll know all about dry, calloused and cracked heels. For some reason, our feet dry out very easily in dry or cold weather, exposure to harsh environments like salt water and sand and lots of barefoot walking. Makes us wonder whether our caveman ancestors spent all their time hobbling around too?

The conventional solution is to use a special natural stone, called a pumice stone, to rub down the callouses and make things nice and smooth again. The problem is it’s a real chore to do, and awkward. So that’s why it’s interesting to see this Powered Pumice Stone, which takes the good old cure and throws in some solid tech.

The battery powered roller stone rotates at 1800rpm, which is more than enough to flay the socks off your dry patches in no time. Or cripple you. One of the two. Nah, just kidding. The shaver sized device comes with two rollers, coarse and extra coarse, and each one lasts up to six weeks. Although we suspect they’ll last longer if you don’t use them very much. The product is priced at $49.95.
