ugh, last time i checked, salomon started making skis around 1980. they might have been around in other markets. correct me if im wrong, but im pretty shure about that. and no. burtons stuff sucks. they only thing Burton makes that any good are thier boards. at least there is alot of technolgy in them. however, thier bindings suck, as do thier stupid ass insert patterns. not only do they not make sense, but it forces compatibilty issues. yes, thier sub divisions make some nice stuff. but most of those companies arnt run by burton, just owned. and no, i do believe burton will make skis, wheter under the burton name or some other logo, burton will be the ones making the skis and the money, along side thier snowboards.
oh yeah, those burton ski boots you saw on ebay, were hard shell snowboard boots for alpine snowboards. they mount to the board just like snowblade bindings, so they could technically be used in skis, but thats what those were.
