Thank you everyone for the responses!
To answer a few questions I read:
The first 5 or so pairs I sell would be full warranty for 2 seasons. If they break you get your money back.
There would probably 2 molds at most. The tip/waist/tail would be the only customizable parts. The rocker/camber would stay the same but there might be 2 lengths or a park and pow ski.
What would I get sued for?
