[pct-l] nerve problems in feet/bigger size shoe needed

[Marion Davison]

I'm taking an informal survey.
After our first year of long distance hiking, Ray started to experience 
  nerve problems in his feet that have persisted to this day.  He has a 
sense that his feet are under pressure, even when barefoot, and 
sometimes a persistent tingle.  Not anything that would be described as 
pain.
Has anyone else experienced this?

Both of us have gone to larger shoe sizes.  In my 30's I wore men's size 
8 running shoes and hiking boots.  Since our first year of long distance 
hiking (1996)I have been wearing men's size 10 1/2.  Ray has gone from 
size 11 to size 13 in all his shoes.
Is this common?  Only among hikers? Or is this a natural consequence of 
aging?
