edges are almost never warranty-able, edge damage isnt covered.
which is idiotic considering companies can get away with advertising things like edge armor and then not cover edges, but alas, what ya gonna do.
basically yeah, you are stuck. but if they are really park only skis, edges underfoot arent essential. i rode a pair of skis missing a shitload of edge early this season, and it wasnt bad other than on ice and things. sure its not peak performance, but on rails having no edges was actually kinda nice haha
