Good Day Downunda,
I too had little problems with my feet. I had a total of 5 to 6 blisters over my entire '99 thru-hike. And none in an area of my feet that caused me to slow down.
Anyway, I have the habit of kicking my shoes off anytime I can and going barefoot.
But, I cannot plead being a great mind. Wish I could. Until I found this website on fitness ( I am using www.cooperfitness.com to train for a section hike and track my level of fitness ), I never thought of it being important. I think it was great that you consciously went out and did long walks in your bear feet. Very smart.
By the way, this site is for free. I calculate that on a typical day on the trail, one does anywhere from 35 to 70 aerobic points using the cooper system. This could allow someone who lives in flat terrain and no tall building with no gym nearby to train for a hike very nicely. It has exercise routines and all sorts of information on diet and exercise supported by one of the pioneers of sports medicine, Dr. Kenneth Cooper.
Mr. Boo
