As the warm summer weather continues, it’s the perfect time to wear your newest pair of sandals, whether they are casual flip flops or gladiator-style platforms. However, before you don a pair of shoes that shows your toes, make sure your feet are well-groomed and ready to be seen.

Calluses, layers of tough skin formed by pressure and friction, can be both unpleasant to look at and uncomfortable. Luckily, removing the annoying skin abnormalities may not be too difficult.

“The safest way [to remove calluses] is to use a pumice stone or file to buff away a callus after a bath or shower, when skin is at its softest,” Rock Positano, podiatrist at the Hospital for Special Surgery in New York City, told Allure magazine. Tweezerman Pedro Callus Stone features a rough side for removing calluses and a fine side for smoothing and massaging feet.

Women can also use liquid formulas that contain salicylic acid, like like Babor Feetness Callus Remover Fluid, but Positano suggests testing the formula on a small patch of skin first, to make sure you aren’t allergic to the product.
