Keeping specific callouses *rough*, diagonals only

[Daniel W. Rouse Jr.]

So I've noticed that the thickest callouses are on the edge of the big toe
at first toe knuckle level, the outside edge of the balls of the foot more
or less aligned with the callous on the big toe, and on the outside edge of
the heel. Don't want to smooth those out, actually want to keep them rough.
A single diagonal crosshatching pattern along each calloused area--one
diagonal way, then the other diagonal way. No horizontal or vertical
crosshatching. Dig in as hard as necessary to move through the entire
callous, but don't create actual cuts. Diagonal crosshatch lines will be
visible, and some fine particular roughness will be visible and felt. Don't
do this any more than twice that one day. Go barefoot again for several days
before doing roughness maintenance on those specific callouses--be sure to
walk on both rougher and hotter.

As additional parts of the toes, the balls of the feet, or the heels become
more calloused--this same maintenance can be done on those. The other toe
pads are less tough than the big toe and will cut more easily if too much
pressure is used on those toe callouses, but they'll also need less pressure
to move through the entire callous.
