Alpinestars S-MX 2 Boots (Size 38 Only) 4.5 5 50 50
Without a doubt best boot Ive ever owned I bought my first pair of MX2 back in 2010, I was immediately impressed. To be honest, like any boot, they needed to be broken in, but WOW. Once they were, I would (and still) wear them everywhere, I probably wear my old pair more like tennis shoes than I do my actual tennis shoes. The replaceable skid pad is also great, being that you can choose different style to go with too. Only bad thing i can say, is the ventilation, its not bad, but its like any other pair.

Good Boot These are really good boots for the money. Protection is great and they are very comfortable. There is no airflow so these are terrible for summer riding (which I'm doing at the moment) but Alpinestars has a vented version of this boot so I won't knock anything off. My only complaint is how hard it is to open the clasp on the strap. I have to just leave them closed as it would hurt my hand trying to get it open, I also had to trim the strap as I couldn't get the boot tight enough and the hard plastic was digging into the boot. Overall it's a great pair of boots. Protection is better than any regular shoe and that's what's really important. July 9, 2015
Awesome boots!!! If you are looking for something more than tennis shoes/work boots, but don't want a full on race boot, these are the ones to get! I have been holding out for the right pair for a long time and I am super happy with them! Go about 1 full size smaller than your normal tennis shoe size. I normally wear a 10 but a 9 in this boot fits me perfect. June 29, 2015
best boots ever I just got my pair of sm x 2 boots and I love em they are very confortable, quickly to put on and take of, very safety, the protect your whole foot, and they are ready to those long rides because they ate very lightly February 16, 2015
Awesome boots I normally wear a size 13 Nike but am in a size 47 of these boots and I have very wide feet so I normally have to go up a size. These are great boots much more waterproof then my faster vented shoes and I love the fact I just slip them on a zip them up after setting the adjustment strap once. These also seem to make it easier to shift. I wear these all day on and off the bike and they are very comfortable. December 29, 2014
right boot, right choice I own a C109RT Suzuki and love this boot. My trips are on an average of 2 to 4 hrs and the S-MX2 is a good buy. No laces, just a zipper, velcro and a buckle lets you get in and out of this boot quickly. Very comfortable, so if needed you can stay in this boot all day. They're not heavy or bulky but still offer great protection. Alpinestars did a good job on this one. I did some research and commend RevZilla for the great video breaking down this boot. I had no problem with the sizing. For me it was spot on. Looking forward to many more cruises. September 27, 2014
Nice Boot! I did a lot of research before I purchased. I ride everyday as a commuter and spirited rides on the weekend. I wear a 10 1/2 US, a 44 fits perfect. Style is very nice goes well with my jeans, I stop at the grocery or convenience store on the way home from work and no one looks at me like I am Darth Vader! Felt great walking in them out of the box. Protection, Nice ankle support and toe box, shifting feel is positive. Kind of warm in the Texas Sun, not unbearable though. Overall Happy! August 6, 2014
Comfy and stylish boot The S-MX2s are really comfortable straight away. I was very happy with them on my first ride. Well done Revzilla I received my boots in Australia five days after I placed my order - really good service. July 14, 2014
