Not really when seen per mile. I walk about two miles every day so
that's around 700mi/year. A pair of $30 sports shoes wears out within a
year so 4c/mile. I get more than that out of a road bike rear tire.
Sandals don't wear out that fast for whatever reason but can't be used
much in winter.
Get rid of the shoes. The feet are self healing and will grow to
accommodate even black top pavement.
Perhaps Joerg should buy a bucket of latex rubber, dip his feet in it and hold
them over a fire to harden the rubber. If pre-Columbian Amazonian Indians
could do it, he could do it.
