Don't you believe the sizing charts; these run small (short) and narrow in the front toe area.  This is especially bad, if you have arthritis or want to wear a thicker sock or a sock liner and sock.  But even if these aren't concerns, these run small.  I usually wear a 9 medium Sorel boot, but in these, even a 10 medium felt tight.  They seem to have good traction in the snow; not so good on ice or slippery/wet floors.  As typical for most lace-up boots currently on the market, the laces are fat and slippery, so they tend to come undone or loosen while walking.  They are a real challenge to tie, as well.  The liners are not removable and could be more generous.  My feet were cold in minutes and there is no room for an additional insole for better insulation.  These boots are fairly lightweight.  There is some arch support, but not like a shoe.  Sorel boots sure aren't what they used to be...
