Sorry, missed this post. But yes they will work fine. Any boot with a slight "lip" or indentation at the heel portion of the boot will work with new-matics. Pretty much any real alpine boot (single or double, leather or synthetic) will have this lip, and will work fine with newmatics
That being said, precise fit varies from boot to boot. If the rocker is really pronounced on a particular boot, the crampons might not be able to flex enough to match the curvature of the rocker. In other words, you might have a gap visible between the toe of the boot and the front of the crampon.
