I am 58.
I love my Full Tilts. I own a pair of the BumbleBee Pros as well as the First Chairs.
I bought a size down (I wear a 10 street shoe). The shell is for a size 9. I have one finger clearance in the back.
I have a narrow foot (C width) and muscular calfs. The Full Tilts fit snug-comfortable on my calfs.
I ski mostly in New England. The Intuition liner keeps my feet warm on the coldest days.
I have a Superfeet green inserts and I made my own heel lifts out of 1/4 foam core, placed under the Intuition liner. I also placed a rigid-thin full insole under the Intuiton Liner in each right boot. My right foot is smaller than my left.
I bought stiffer tongues for the Full Tilt boots.
I have replaced instep cables twice on the First Chairs. I really crank it down.
I replaced one buckle on the BumbleBee pros.
I also own a pair of Head RD 96s and Doberman WC 150s.
