As for the Stubais, the model in question here probably is the "Ultralight Universal" ($135), a simple, flexible, ten-point crampon with moderately aggressive points and a binding system that allows them to be used on just about any kind of footwear. They'll be fine on your Asolo Fusions, although I think the Fusionsa terrific bootmight be a little low and light for the snowy summit of Shuksan. But for one trip, assuming you have a decent pair of gaiters over them, they should be fine.
Generally speaking, in fact, I think that most people use far more crampon then they needparticularly for modest glacier/snow slogs such as you find on Shuksan and the standard routes on just about any big volcano (Rainier, Hood, etc.) on the West Coast. Crampons such as the Stubais are light enough (20 ounces for a pair) to pack for most trips without giving it much thought, and will work on basically any boot you're apt to be wearing.
