I find it Strange, Malamutes, Driver X, Booster Straps and all the rest of the How to Make SB Stiff, I have had All the Stiff Boots and they break down after 14 days or so...simply lock the High Back Up, then add a top strap, yea, you can Adjust the Top Strap to exactly the Stiffness you want...Meaning leave it loose and full Ankle Flex, tighten all the way and remove the Ankle flex, while adding Lateral support... At this point, what with Carving making a showing, I am surprised No Body is making a 3 strap...There is no way the Step in Boots don't just Break Down after a couple weeks of use...though having that Heel Locked Down does make a substantial improvement I would Imagine...
