Thanks for the advice, Jack was awesome! I cannot believe how detailed he was in making sure the boot fit properly and then tweeking them the following day. In total we spend about 3 hours for the 4 of us.
I was not surprised to find out I was skiing on 1 size too large boot but my brother and sister in law were skiing on boots two sizes too big. No wonder why she had pain in her lower leg.
I was surprised though how skiing on properly size boots took me a few runs to get used to. At first is wasnt comfortable and I had to stop half way down a green run and take my boots of for rest. But after that they felt much better and I noticed the difference in the ski response.
Unfortunately I purchased the boots late in the trip and only had one day to use them.
So if you are in Snowmass looking for a boot fitter check out Jack. He is in the building next to Venga Venga and works as a sub contractor aspen snownmass (I believe)
