Proven for what? That’s what’s left out.
So they spent $750k, just on marketing and royalties in the 1980’s. Wait, how long after that did they go out of business?
conversationally, guys, a couple of observations -
Caber was purchased by Rossignol - still making boots today...
ski boots in the late 1970s was Dominated by Nordica and Lange. dominated.
Caber had tried to find a niche with external tongue designs -
the Caber Bio was a modified external tongue design ;
it was marketed to be a descendant of the Alpha, But it wasn't - it was a Very different boot !
( Caber's other top boot in '79 was similar, but had a molded closed-cell foam liner of the era ; I believe the cuff attachment was also different, but don't hold me to that - I know this was a significant difference of the top Dolomite's of that time... )
I will give Eisenberg's innovation a pass -
it was certainly consistent with other bio-metric ideas of the era.
I still cannot wrap my head around the part of Eisenberg's idea and a couple of posts in the thread that are promoting the idea of movement of the foot ( it's Not articulation. Articulation is simply the contact between the bones - it does Not mean movement )
... movement of the foot within the boot !
everything I have understood about optimal boot performance for too many years to acknowledge promotes the idea that all forces from the leg-and-foot are transmitted through the boot to the ski ! ! The idea that my foot would move within the boot before engaging the boot to engage the ski ,,, sounds scary
( or at least 'WarrenMiller comical' )
it had to be maddening to the executives at Caber that Ingemar cobbled his Alphas for a decade -
but that was Ingemar !
( Caber would have probably been better off to keep the Alpha in the line, and simply market it as, Ingemar's boot.
I bet I would have bought a pair in 1979 !
I also had an eye on Lange's racy new XL•R ! !! )
it was a long time ago.
Sometimes, it feels like the blink of an eye !
Thank you. skiJ
