dont listen to the haters, my brother bought a size 31 nordica boot from a ski swap. he wears a size 11 shoe. he skied those mech-boots for 4 seasons straight.
he even painted dragons, knights and wizards his too short, old, midsole marker-mounted volkl expressions. good stuff.
needless to say, using gear that wasnt right for him made him hate and suffer through skiing. dont make the same gaperish mistake.
my advice is to use gear that works properly based on your needs, not wants.
