You could never tell by the gleaming chip-free polish on my toes that there is a horror show happening on the soles below. Walking has been my main source of transportation for the last 10 years and I have the callouses to prove it. Trips to the salon soften things for a few days, but I need something to use at home in the week between visits; that’s where the Emjoi Micro-Pedi comes in. Unlike metal scrapers and razors, this battery-powered foot buffer smoothes away callouses without butchering the tender skin beneath it. Now, who wants to give me a foot rub?
