Had tried on the Vasque Breeze II and liked it, but reviews said it wasn't waterproof so I returned it and bought this St. Elias which runs so much wider that it loses all ankle stability.  I even tried adding an insole.  I need a sturdy waterproof backpack boot for my narrow, high arch size 6 foot that can take me up a traprock (sharp loose rock) mountainside.  Any suggestions?
