First I will warn everyone, if your in the middle of your size range don't get the next size up. These boots run on the large and wide side. I normally wear a 12.5 but most shoe companies don't sell half sizes above 12. As a result I buy size 13 shoes. I decided to get the 13 (49) and had to send them back. They were way to big. I now have the 48 and they fit good but still have a little play. Once I put some better inserts in and wear my riding sox they will fit excellent. I can't report on airflow yet but from what I can tell they should breath well. There are several plastic vents on the boot and I tested each by blowing into them with my hand inside the boots. They all allowed the air to flow freely into the boot so they are all functional. Add to that the front perferations and this should be a good flowing boot. The protection and features are outstanding for the price.

I bought the vented version of these boots because the Sidi On-road goretex boots that I normally wear were "cooking" my feet everytime. I used the new boots yesterday for the first time in 90+ degrees on street (no highway) riding, which I would consider the warmest type of riding because of the frequent stops and not reaching above ~55 mph. The difference in temperature was noticeable, not that you feet air moving through your feet but you do not sweat profusely. In addition, they do not seem to need a period of break in, the fit was excellent (for me at least) and did not feel stiff like other boots do during the first days of use. It is hard to give an assessment about the protection but they have more protection built-in that my Sidi boots, which are comparable in price. Also I like that I can wear them inside my pants and in all black they do not look very flashy.
Yes, I recommend this product.

I commute everyday and these boots have been great.
Very comfortable on the road and walking around.
Took me about 5 days to break them in.
Good protection around the ankle without reducing mobility.
My girlfriend has the same pair in the ladies cut and she loves them as well.
Sizing chart was accurate, im an 11.5 and i got the 46 euro.
Yes, I recommend this product.

Great riding boots for the money. I would recommend these boots for anyone trying to get some good riding boots, but not full race boots. I've worn these out riding and then gone to the movies, and even went to a park for a festival and walked around comfortably.

From Ft. Lauderdale, FL
This is my first race boot and they are much more comfortable than I imagined. I was at a track day event this past weekend and had them on for 4+ hours with no problem. Although I thought they were a bit snug at first they offer very good ankle stability so being snug in that area is a good thing for protection. My foot is a size 10.5 and that's what I ordered so they fit true to size. They seem to vent well and are fairly comfortable to walk around and fit well under a pair of jeans or over a race suit. Great value I think and would definitely recommend these boots.
Pros Rugged, Comfortable, Fashionable, Great Value
Yes, I recommend this product.

These boots replaced an aging pair of Alpinestars boots when the left sole and shift area began to fail. I called to check on sizing as my boots did not have an indicaiton as to what size they were. Ultimately, I chose to follow the Revzilla recommendations and they fit perfectly. Very comfortable.

Cons None
