Changes

Salt water will dry out the skin, causing it to thicken slightly. I have found that this technique works, but the effect is very slow. Bathing the feet in warm salt solution can also be very soothing, a benefit beyond any toughening. I found using Epson salts rather than table salt is no more effective, but it does boost your magnesium [[Magnesium]] intake.

The tannin in the tea is supposed to bind with the protein [[Protein]] in the skin and make it tougher. I tried it a few times, but found no real change.

A callus is a localized thickening of the skin. A callus is a bad sign, as it indicates localized pressure or rubbing, which means your shoes [[Shoes]] are probably not fitting well. The best thing to do for calluses is to remove the root cause. I keep any calluses filed down and moisturized. I have found that moving to primal running has removed the root cause of my calluses, and they are disappearing now.
