JaneB I just purchased the exact same boot
I love these boots - I am an E width with high insteps, narrow ankles and large calfs.
Do you have a custom footbed or just using the stock footbed?
I got a custom footbed made when I bought the boots and after skiing 2-1/2 days, came home with blisters and bruises on my toes and arches. The footbed guru at my shop did a lot of trimming to the bottoms and edges of the footbed. He also ground down the base board under the liner, which gave me more room around my little toes. He made the base board level with the bottom of the boot, creating a seamless transition with a lot less stuff in the way.
I have also gotten in the habit of buckling my boots a bit looser than I used to. To my surprise, it has actually improved my skiing and my feet are comfortable all day (I only pop the buckles open on the first two lift rides of the day - after that, I can even walk to the car with the buckles done up).
I saw on another post, that fitting the footbed is more like "voodoo", it is an art, and is only glossed over in most of the "training" classes the manufacture holds. The guy that actually made my footbed is not the one that did all the fine tuning.
Mark on your foot with a sharpie marker the exact places that hurt or have too much preasure and go see the bootfitter. I assume the boots were comfortable in the shop.
