Sidi Discovery Rain for DS/Adv Touring duty. Love this boot. Great protection, comfortable from the first day and waterproof. On the downside, they can be hot down here in Texas (but then again, everything is hot down here, it doesn't matter what u wear). I took the metal toe caps off as they provide zero traction on the tarmac and tear up my hardwood floors. Size 44 euro/size 10 american. Price: 240 on ebay.
Vertebra 2 for zipping around town on my R1. This boot fits like a slipper, has held up through 2 wrecks, and after 5 years and tens of thousands of miles, it doesn't have a single thing that's even starting to come undone on it. I have no doubt this boot will last for many more years. Size 44 euro/10 american. Price: 180. don't remember the name of the bike shop.
