Knot, I have a few pairs of those too, but even in wool socks and merrels my feet were numb in my office til lunch yesterday. It should be warmer for a couple weeks though. Chaco actually made trail shoes for awhile but I can't find enough info to see if the footbed design was similar.

yellow - the "chains" I meant were boulder running co & runners roost! but I think Colorado running co is opening a new store in Lakewood next week. If I read their website correctly, anyway. I ruled out a few more pairs today so maybe that'll be the last store I have to go to!
