Denco's 3981 Half-Pipe Foot Smoother is made in Germany and features an extra wide surface for quick, efficient smoothing. This double-sided tool has both a medium grit and a fine grit to effectively reduce and smooth calluses. You'll love the deep, concave side because it cradles the heel for maximum smoothing. The convex side is great for the balls of your feet. The smoother is extremely lightweight which makes it easy to control and comfortable to hold.
