I have SIDI Vertebrae Corsa boots. They don't look storm trooper-ish like Alpinestars do. Your jeans will easily slip over the SIDI boots. I had 3 racer friends of mine all get new Alpinestars boots in the beginning of the 2006 race season. About 6-8 race weekends and a handful of trackdays later each one of my friends had duct tape and/or some kind of super glue/gorilla glue holding the soles or other pieces of the boots together. Plus, neither one of them crashed in them. I've had my SIDI's since 2003, I have at least 70-75 trackdays, 49,000 street miles, and about 15 race weekends on them and there isn't a single broken stitch. SIDI's hands down beats Alpinestars in boots. Alpinestars squeek more than SIDI's do as well (my SIDI's don't at all anymore). I always wear my boots when on the bike, even if going to the mall...when I rode to the mall that is. They are more comfortable than most of my shoes.
