What's the damage?
Basically, officially no, they wont (their warranty is voided by rail damage). However, most companies (Line especially) will warranty certain problems even though you've hit rails with the skis. However, edge damage and most base damage is usually never covered - but if it's a delam/topsheet problem, they've snapped, or their are core problems usually you can get that taken care of.
