What are MadJacks?

The MadJacks is a simple idea.  The MadJacks adapts your snowboard boot to a standard ski binding.  Once you are in your comfy snowboard boots, step into your MadJacks and then into your ski.  Off you go for a great day of comfortable skiing.  Oh, and when your head in for lunch or back to the lodge at the end of the day, step out of your MadJacks and no more Frankenstein walk.

Who are MadJacks for?

Everyone that wants a great day of comfortable skiing.  Why not, you deserve it.  It is possible.

Does the MadJacks work with any brand of snowboard boot?

Absolutely, Mad Jacks is universal with all brands, including those that use single boa technology.

Does the back support of the MadJacks lock into place?

The MadJakcs uses an industry unique system to keep the back support from rotating backward providing the leverage you need for performance.  In addition, the ankle and calf strap create a "cinching" mechanism around the snowboard boot. The MadJacks and your snowboard boot generate all the stiffness you need.

Is the MadJacks Safe?

Yes, the MadJacks is designed to all ISO and ASTM standards related to alpine ski boot geometry (ISO 5355). The MadJacks has also passed release testing. As such, the MadJacks with a standard snowboard boot behaves like a standard alpine ski boot.

Will I need to adjust my bindings?

Maybe, but only just a little. The snowboard boot/MadJacks combo is normally a bit longer than the size ski boot you would wear. However, the difference is relatively small and you should only have to adjust your bindings outward a small amount. You should not have to re-mount your bindings.
