I would go to Pepi Stiegler's in the village when you head out to jackson. They hook it up real well with prices and are the best boot fitters in jackson.
You need to ask for "Bootsie" he's the man! I wont have an of my boot fitting done anywhere else.

There are two shops at the village the small shop at the base (ALPENHOF)
ALPENHOF
3255 W. Village Dr.
Teton Village, WY 83025
Tel: (307) 733-6838
And if Bootsie isnt at the small shop go to the OLYMPIC PLAZA. And ask for Scott Smith.
