Thing with boots is, you have to know what you want from them. Its not really just about them being comfy if you ski at any sort reasonable level.
Its really not that hard to fit a set of boots that someone will walk out of the shop and think, these are comfy.
Ski boots are often a compromise between performance and comfort. So you need first decide where along the scale you want to be.
If you want a pair of boots to cruise around the piste and not undo them all day. You need something different to someone who wants to do mach 1 for 3 minutes and undo them on the lifts.
You may be a Level 10 skier on there scale (what ever scale that is) but might want to spend your time in comfort even though you could do an Olympic downhill run at warp speed.
So just make sure they ask you the right questions.
