BUT - These things are inheritly dangerous. The non-release bindings increase the risk of Tibia/Fibula Sprilal Fractures by 4 to 12 times. ((Like the old days with skis without release bindings)). I should know. I just broke my tibia and fibula in 5 spots 2 months ago at Heavenly.
I beg all manufacturers including Dynastar and Salomon to produce ski blades with RELEASE BINDINGS.
((It might cost a bit more to manufacture, but it sure would make the product a lot more safer..))
