I'm doing some research on step ins.
My brother designed a step in about 10 years ago that would work with any soft boot. Its been patented, and he did get some interest from some of the manufactors back then. The binding also uses straps that can be preset for the desired tightness.
I really thought he was onto something at the time but I couldn't help to introduce it to companies (was super busy with my own projects). I was a freelance photographer specializing in snowboarding during '88 - 00.
What I want to know is there still any interest out there for a solid system that works with any board/ soft boot?
