Yes! But not at the same time. Our BMF bindings are Future Proof, in the sense that you can use the same binding for either 75mm or NTN boots if you have a Conversion Kit. No binding is compatible with both types of boots because 75mm boots are asymmetric, having a distinct Left and Right, and a longer part of the sole sticking out (the "Duckbill"). NTN boots are symetric at the toe and have a much shorter sole sticking out the front. Snag an NTN Conversion Kit or a 75mm Conversion Kit to switch your BMF between the two boots standards. It's not something you can do on the snow, it requires some tools and time on the bench.
