Mark Pittsburgh,  PA Affordable Full Leather Boot Really good fit. I wear a 10 Merrell and Puma, 11 Adidas, 27.5 Dalbello, and 43 Specialized and found these fit well in a 43. Casual enough to wear off the motorcycle as far as comfort and appearance. Not terribly hot and I enjoy wearing off the little plastic toe guard!

Stephan Melgar brandon,  MS Great boot I have had these boots for awhile now and I have to say I love them a lot. I wear them on the street and on the track and I feel very protected in both conditions. I wanna get another set but my wife wants these too look worst. Buy these boots you wont regret it. BTW I had to get one size smaller, great return policy>

Gary Port Orange,  FL great boots Have put a couple thousand street miles on these boots. I would think that if I put any track time in, these boots would work out great. Fit is great, comfortable over the long haul, and didn't require much break-in time for me. I wear a size 12 shoe and ordered a 47 originally. But these boots fit me at a 46 which according to A* is an 11.5. Return and exchange with Motorcycle-Superstore was a piece of cake.

Rich Long Island,  NY Great boots These boots are excellent. I like the feeling of protection you get with them. They run a little large so I needed about a half a size smaller. Also I like the velcro on the inside because it allows for adjustability. I wear them for everyday street riding and although they are track boots they don’t look like too much for the street in the all black color with a pair of pants over them. Overall very satisfied with my purchase I would definitely recommend them.

bill harty bartow,  FL alpinestars = awesome Pair of boot's Started wearing the boots the day they came and wow what an awesome pair of boots. Read the past reviews, big help. I wear a size 11, 46 boot. Review said they run big so I ordered a size 10.5, 45 and the fit is perfect. Great price from Motorcycle superstore and free shipping. Good boots for short or long rides I walked around most of the day for a bike show and they felt great but I did have a lot of bike riders stop me and say wow nice boots. Just say Motorcycle superstore.com great customer service.

tom minneapolis,  MN happy with boots so far In the two weeks or so that I have been wearing these boots they seem to be a good value for the money. I was concerned that my feet would get too warm wearing them but so far this has not been the case. My only complaint is that the flap that sits under the zipper doesn't always sit nicely and takes some fiddling to straighten out.

Chris Klemp Las Vegas ,  NV Alpinestars S-MX 4 Boots Once I was able to nail down the size that fit me the best; they seemed to be running a bit big in sizes. I was very impressed with the fit and feel of the boots. They feel great when riding and allow me a good feel of the shift and brake levers. The boots are holding up very well. I feel these are well worth the money and will last me for quite a few years.

Max Van Laar Abbotsford,  BC Nice boots The boots fit light, and comfortable. The Velcro covering the one side of the boot can be a little annoying. For the cost it is one of the best boots u can get.

Mark North Bay,  ON These boots are good!! I have a wide foot and these boots fit well right from the box. Sizing is spot on. Materials and workmanship are excellent. They are initially a little stiff but are loosening up nicely. They are comfortable and you never notice them on the bike - also comfortable enough to wear around work. At first I had trouble missing up shifts because the "feel" is not as good as my sneakers but now I have adjusted. They are well enough vented to not cause your feet to sweat when it’s warm. I would definitely buy these again.
