I am going to be buying my first pair of ski boots after renting my entire life and am looking for some advice on what type of flex I should be looking at and sizing questions. I realize that it will boil down to trying on different pairs and working with a boot fitter to get the best fitting boot possible but I am looking for a starting point so I have an idea of what boots to research via reviews and such.
A little background about myself to hopefully help get me going in the right direction. I am 28 years old, 5'10, 160 pounds, and have been skiing once a year since I was 6. I am getting to go out to Breckenridge twice this coming year for a total of 12 days of skiing and decided it was time to get some custom fitted boots for more comfort and responsiveness. I really don't know whether to rate myself as an intermediate or advanced so I guess I fall between the two. I can ski almost any black at speed and enjoy getting in the bumps and powder when I get the chance. I ski some double blacks but I am held back a little because of lack of days on the snow and the use of rental gear. I plan on taking some more advanced lessons while out on my trips this year to help me in steeper and more technical terrain.
I have been looking at the new Tecnica Mach 1 120 boots in particular along with Lange and Dalbello boots. I am just unsure if I should be looking at boots with a lower stiffness and what other factors I should be including in my search. I am going to be in Breckenridge in October hiking and want to stop at a boot fitter while there and hopefully get them before the season starts. I appreciate any recommendations on boot flex, size ( I wear a size 9 shoe so I'm between boot sizes), or a certain boot in particular. Thanks
