after hundreds of railslides my edges eventually fell off and then the base separated from the sidewall of my skis and then water got into the core and then I landed on my tails and my ski broke in half. Dynastar said that my skis didnt break from a defect but they broke from rails. THey gave me a pair of old demo skis to use though so it was good.
jsut contact the store from where u got them and the company, some will help u out some wont, rails is hard to say 'umm, i was just skiing and ummm the rails wore down under my boot'
