I am really new to skiing, loved it. Rollerbladder for almost 25yrs, Fit Female age 40. Normal to lighter in weight 5'8, 130lbs. Live in Milwaukee WI. I am also good at ice-skating, cross country skiing, running, year round-biking. So I decided I should buy some boots because my toes were so cold in the rental. Anyhow, after my years of rollerblading, I know how important a good fit is. When I stand a few toes touch the 24 mark on the shoe mark? (no idea what you call that!).
Since I am a new skier (black diamond first day out, no problems hockey-stop, turning--this is WI though, Alpine Valley, how hard can it be!) the place I went to try boots first fitted me into a really soft/plush boot. I hated it. I can't imagine skiing on something so flexible. Likely because I I couldn't see myself rollerblading in this booth either. So he suggested I try one of the more advanced boots.
The boots I liked ended up being Salomon XPro 90 verses Quest Pro 100.The x90 was size 23.5 and my toes touched the top and I lost circulation in my foot. I actually lost circulation in every boot I tried on. I have a really high instep, wide foot bed, narrow heel. I could feel something hard on the bone of my arch (top), the boot fitter said after a few wears the boot would get bigger and since this is a customization boot they can bump out the area hitting my bone. Well, me being new and boots being pricey I am dubious and need to be cautious. Overall, loved the boot, wouldn't last a day with zero circulation in my foot. Out of the 10 pairs I tried on this and the Quest were the best fit and feel for me though.
I then tried on the Quest Pro 100 in a 24. Loved it. They did not have it in a 23.5. I could feel my foot, no loss of circulation. My heel doesn't lift, I just felt the toe box had more room. I could wiggle my toes more. My toes did not touch the top. The boot fitter said it looked to big. Look feel are two totally different things. I would buy this boot but everything I read keeps saying buy a size smaller than you think, so it the XPro 90 the boot I actually want but I am too new to understand why?
