These Endurus XCR Boa trail running shoes by The North Face are relatively light at about 16 ounces each, and they're made of waterproof Gore-Tex which is breathable but keeps those feet dry. Their most unusual feature is the lacing system that lets you tie your shoes by turning a special knob, dialing in an even and reproducible tightness that can't come loose.
Here's my road test verdict:
I like the way they look, but I ordered size 11 1/2, which I usually wear, but they fit too small. It felt like something was rubbing against my toe, and after a couple of miles I had already raised a blister. I'll be sending them back, and seriously considering whether to order another pair since I'm not sure whether a half size larger will fit or not.
I'm thinking of finding a local store that carries them so I can try them on first. If you do order them, remember that they run a little small. Cool technology, but I'm not sure if they're worth $130.
