I've boughten 3 pairs of boots from Colorado ski and golf. Some of their sales reps know their stuff but most are full of it. My experience with some of them is that they dont listen to what you are saying you want or how you ride, and they just try to sell you what they have in stock in your size. So I recommend you do some research first.
They do have a guarantee fit program though, and will tweak your boots anytime for free. I had some heel slip on my burton driver x's after about 12 days. Christof at the Littleton locations was very helpfull, and threw some new jbars in them and told me to come back if I continue to have issues and they will try some other things.
