These boots will definitely work with 75mm cable bindings. However, depending on the ski (and skier,) the Riva Z Comp is probably not a great pairing with this boot. With its compression springs, it is more oriented towards downhill performance at the expense of touring ease. These boots are at the other end of that spectrum. Which is not to say that it's not worth trying, or that you can't have fun with that setup.

Yes, that is what I bought them for. You are not going to get as much support for hard turns as a plastic boot. You can see the heel photo on the mens version at:||http://www.sierratradingpost.com/i/66492,,2_Alico-Backcountry-Touring-Nordic-Ski-Boots-75-mm-For-Men.html
