DOUGLAS J I own a pair of Scarpa Mont Blanc GTX boots and they fit my boots perfectly. I looked up the ASOLO North Boots online and, from my internet research and looking at images of your boots, it appears that you should have no compatibility issues using your boots with these crampons. Having said that, it is only a recommendation and not a fact. Check with Sunny Sports on their return policy just in case, but it appears they will work. These are pretty standard crampons and work with most mountaineering boots that have prominent heel and toe contact points.
