Calluses on the feet can be annoying and are considered a blemish by many. But how can you get rid of them? Callus-reducing foot creams promise a remedy. Stiftung Warentest tested whether they really offer this. Nine creams from drugstores or pharmacies had to prove themselves on the feet of 20 test persons each (prices 2.84 to 23.00 euros per 100 ml). Result: No product failed the test. Three creams even lead to visible results within a few days.
