Being an engineer, I'm worried about the compromised of the binding or ski rail structural integrity of the flex that did to the binding itself or the ski rails.
My ski set is the Volkl AC unlimited with marker motion LT 10.0 bindings.
Good ol' SportChek!
Really, unless he took a hammer to them, I think you'll be ok..... most rail systems have a little tolerance to them.
Were they new from that shop? If so ask for a new pair...... If they were bought elsewhere, then i'm not sure you'll get anything unless they actually caused real damage.
Do both bindings on both skis have the same amount of play on the rails? or is the "damaged" one more loose/tight?
