Uh…Roy, they’re pretty much the same shoe. The Spyre GV ($195) is a lightweight trekking boot with synthetic/leather uppers, Gore-Tex bootie, Vibram sole, and a reinforced heel. The Superfly GTX is a…lightweight trekking boot with synthetic/leather uppers, Gore-Tex bootie, Vibram sole, and a reinforced heel. True, you can get the Euro version in a sort of styling wine-red. That is about the only difference. So I wouldn’t fool with trying to order them from Europe, pay extra freight, and then risk the need to return them for a different size.

Besides, there are LOTS of boots in this category, so you are sure to fine the right fit locally. There’s the Kailash ($199), also a light trekking boot with uppers that combine suede and synthetic fabric, a Gore-Tex membrane, and a light nylon shank. These are fantastic boots, one of my favorites. Or try the Vertigo Lights ($180), which have a little more leather in the uppers, and an interesting membrane that combines eVent waterproof/breathable fabric with Cocona activated carbon, derived from coconut shells, which reduces foot smells. Or the Cascade GTX ($180), which has pretty much same specs as the ones I just listed.
So get to a local outdoor store that handles several makes, and try them all on. Go late in the day, when your feet have swelled up a bit. But avoid early evening as the store will be too busy. You want to have time to talk with a salesperson and have his or her attention. You’ll find that every maker’s boots fit a little bit differently, and that one will most closely conform to your own foot shape. That’s the one to get.
