Dan S. MacAbre formulated the question :
It's not a problem (other than that the thick areas can get a bit numb,
which I worry about) - I just prefer to get rid of it.

Me too, it is surprising how much nicer my feet feel, after I do them.
What I don't like is the thick three cornered shape of the pads of my
smaller toes and spend ages trying to reshape them back to live skin.
