I run a lot and unfortunately tend to callus formation (incl. All of the nice side effects such as cracks & Co.). Therefore, I once recommended the products of Gehwohl my podiatrist. For a long time I have used Gehwohl Blue (also highly recommended) and am rather stumbled by chance on Soft Feet. Out of curiosity, I tried it and I must say that I really like. It has a very pleasant smell (not as much of herbs such as blue) and nourishes the feet very well.
I use it daily in the morning after showering (and rubbing with a pumice stone) and have since been no more problems with rough feet or cornea. If necessary, I use it several times a day, especially when I have traveled longer distances. It absorbs quickly and feels good (best right after the application in socks to increase, otherwise it is a bit slippery).
