I've ridden a Nidecker Escape 174 with Catek Freerides. Not a full on carving setup, but pretty close. I don't have the stiffest soft boots around, and was able to crank turns no problem. It was actually the first time I was ever able to grab an edge in a heelside turn. I rode the front binding somewhere around 45 deg. Granted, it wasn't the best for side support, but it did work.
