Aerostich sells a "Combat Touring" and "Combat Lite Touring" boot, which are both made by Sidi.
I've been wearing my Combat Lite touring boots for three years now, and have about 30,000 miles of riding on them. They look like they're good for at least another 30,000 miles, if not more.
This Seattle-area 'rounder is pleased to report that the boots are completely waterproof - and nice and toasty in cold and cool weather. When it gets warm outside, I'll wear two pairs of thinner socks to help manage the moisture that accumulates inside.
I did add a pair off "SuperFeet" insoles to make the boots more comfortable for walking around.
I highly recommended these boots!
