Well if you go up to Stevens pass, I would HIGHLY reccomend Sunshine in the demo shop. He worked quite diligently to get me a good fit on both my ski and snowboard boots and was extremely dedicated to making sure I was happy.
They are a fully equipped boot fitter with the ability to heat and mold your liners, make you custom foot beds (takes about 45 minutes), add j bars or anything you make need for good heel lock.
Honestly I cannot day enough good things about Sunshine (John). He is the best boot fitter I have ever worked with. And if you are happy with the service be sure to tip/toss a 6 pack for your boot fitter!
