Thanks for all the replies and suggestions. Please note for record...the issue is NOT, NOT, NOT with the boot sizing. I can wear a thin pair of dress socks that have good wicking and be OK for short periods. Yes, the heavy/extra cushioning comes into play on days where I walk a lot. Again, not a boot sizing issue.
