Since pumice is coarse and porous, it's great for exfoliation. The best pumice stones for feet are especially effective at removing rough, dry calluses. That said, in the beauty world, pumice stones now include those made from volcanic rock as well as other materials,like SiliGlass and ceramic, that mimic porous consistency and function the same, but do have the potential to contain chemicals — so how can you guarantee you're buying a good one?
Pore size is a good starting point and can tell you how exfoliating the stone will be. Smaller pores are smoother and so better-suited for sensitive areas like knees and elbows — while larger pores are rougher to effectively remove dead skin and stubborn calluses. When it comes to pumice stones for feet, the larger the pores, the better.
Next, look at the pumice stone's shape. Flatter areas are ideal for getting leverage on larger sections of skin, like the foot's heel and ball, while rounded edges help you reach into contours. A combination of flat and round surfaces is great for your pumice stone's versatility.
Finally, some stones offer additional convenient features, like a handle, a drying string, or even a motorized tool.
These four pumice stones are some of the best on the market — and with hundreds of reviews to back them up, you don't have to blindly pick one off the drugstore shelf and hope for the best.
