In watching the Men’s Downhill at Garmisch on February 1, 2020 it was immediately obvious to me that most racers had their shaft buckles and especially their power straps on their boots far too tight and this was restricting the ankle flexion needed to absorb terrain changes and perturbations in the snow surface. It was painful to watch talented athletes ski so badly. The pleasant exception was Thomas Dressen.
In the 1980-81 World Cup Season Steve Podborksi won at Garmisch using a dorsal technology that maintained the position of his forefoot on the base of his boot without obstructing the forward movement of the shank of his leg that occurs relative to the dorsum of his foot during ankle flexion. Podborski won Garmisch again in 1982 and 1984 in what is called the Garmisch Trifecta. Only one other racer has ever done this.
Podborski is still the only non European to have ever won the World Cup Downhill title. Forty years after I invented and patented the dorsal restraint technology that enabled Podborski to compete and win on the most difficult downhill courses in the world with a partially healed reconstructed ACL If anything ski boots have gotten worse in terms of compromising ankle flexion and racer balance.
Reading my post The Shocking Truth about Power Straps is a good start. But you have to actually apply the principles as it seems Thomas Dressen did at Garmisch.
