This summer I've been designing and testing my ski bindings.
I want to stiffen and stabilize the heel. The answer is an adjustable aluminum heel strap. I mounted a pair of Weber bindings on a set of roller skis. The result is good but I get a lot of stares as I ski by wearing a huge pair of white winter mukluks in the summer heat!
We are also working on a totally new design that I hope to test in Antarctica later this year.
