Replying to Falcon 9's

Kinda long, I apologize.

Ok so I just got back from my local shop and picked up some Falcon 09's.  Basically I have retartedly shaped feet, "pins and needle" sensation, parasthesia, basically lots of foot pain.  So this shop guarantees boot fit for one whole yea, aka if they don't ski right, I can return them/exchange them for full credit.  I had a great bootfitter with over 20 years experience so I trust this guy.  He recommended these even though I told him park -> all mountain.

Ok, so I'm 6'0'', 180lbs, 20 years old, expert skier.  The boots are 100 flex and I can flex them very far.  The only thing I was wondering about, is 100 flex too much for freesking?  This is my first time buying boots in over 5 years so I don't have too much experience in the process.  The fitter spent over 3 hours shaping the boots, and he did a LOT of work, but they seem to solve my foot pain.  The dude also told me to come back after 2 days of skiing and he will do whatever further modifications are needed.

After coming home I looked them up and they are "race" boots.  Does this really mean anything? As long as the boots fit right I should be fine right?  I looked up some threads and people said race boots will give me very bad shin bang, but these seem to hold my thighs really tight, so I hope that won't be an issue.

Thanks,
Jake
