I just lend a pair of racing skis to a great lady skier ( expert level) and while adjusting her bindings I noticed a major boot error!
New boots ( just one week) ,,yet canting screw was way way off to lateral side ( off center)!
Please check your boots before leaving store! If sales person does not do a simple plumb line test or T square test,,,,consider going to another store!
It will make a world of difference!
