I rode Salomon F20s the past two years and found they were a great boot. But the Salomon speed lace system is not as good as others, such as Burton. This year I switched to DC Status boots and so far and really like them. I also have narrow feet and find these fit very well. Also, the dual Boa lacing system is really easy and fast.
The Status is DC's stiffest boot. If you want something a little less stiff, the Judges are a good boot for that.
