Alpinestars Stella S-MX 5 Boots 4.7 5 29 29
I absolutely enjoy to wear these! I can never give anything 5 out of 5 stars because in my opinion that's a meaning of complete perfection and let's get real. These boots are extremely comfortable to wear while riding. I don't have any issues with the feeling of my feet being over heated. So airflow is great! I do want to point out if you have somewhat of a wide foot please read the size chart before purchase. My size fits great but I'm glad I went with the 8.5 instead of the 8. In my opinion they seem to fit snugg and there's not much wiggle room to stretch! (Typical, they are boots after all!) Overall I'm so happy with the purchase of these and can't wait to continue to ride with them. May 24, 2016
This is my first pair of sheos, I like it very much! It has good prices and decent quality. I wear it for my track day it is great fit. May 17, 2016
Durable, stylish, and practical! Just put my first 800 miles in these boots and they are awesome! I have them in black and they fit true to size. I would say that they are a perfect all kinds of weather boot, with the exception of riding in the rain because their airflow is so good that my feet get wet and cold after a while. Other than that I love them, never gotten in a crash wearing them but I assume they will hold up. I scraped my boot while leaning too aggressively and the toe sliders seemed to hold up! I would definitely recommend to anyone who asked! January 19, 2016
Very comfortable Very comfortable. Unfortunately I haven't tested it out on the roads just yet due to the winter season, but walking around in it is very comfortable. December 7, 2015
Great Boots! This is my first pair of motorcycle riding boots (I had been wearing hiking boots up to this point) and these boots are a home run on the first try. Great fit both on and off the bike. They go over my track pants and I can wear my boot cut jeans with them for weekend touring. I wear a size 8 shoe and the EU39 fits perfect. My feet were comfortable during the warm summer months and now with the cooler temps (45*) my toes are staying warm with thick socks.

Love these boots! I am so happy I finally found these boots! I have tried many, many different boots, and none of them were as comfortable as these boots, right out of the box. I normally wear a size 8M shoe, so I bought a size 39 in these boots and they fit perfectly. They have great protection features (which I hope to never put to the test, lol), the toe isn't a huge box so it's easy to get under the shift lever, the toe box doesn't crinkle up and cut into the top of my foot when my feet are back on the pegs, and the shaft is wide enough that they're comfortable in the riding position but not really huge where you feel like the boot is just flopping around. I didn't notice a lot of airflow in them, but my feet didn't sweat either. I love the style and the color scheme, they just look really sharp. And I'm so happy with them that my husband is buying Alpinestars boots now too! September 8, 2015
Still going strong These boots have so far taken me through 3 riding seasons and are doing well. Very comfortable to walk around in, easy to get on and off, and fit snugly, especially in the toes. I'm stubborn and wear them well into the winter months, using toe warmers once it's below 40F (despite there being not quite enough room to fit the inserts). I don't advise this - they vent well. Still very satisfied with this purchase. Should I lay it down and damage my current pair, I'll probably be getting these again. May 20, 2015
Crammed Toe Box I have had these boots for a few years, and if it weren't for one thing - I would LOVE them. However, not long after purchasing them, the leather beneath the shifter pad on the toebox became dented in from shifting. It wasn't so bad at first. I'd pop it back into place only to have it dent back in. I've tried to fill the boot and get the leather to reform to it's original place to no avail. It wouldn't be a problem, but the rubbing from the dented leather really grinds on you after a while. And, if you're out on a ride and need to walk around for a bit - be prepared to have your toe rubbed raw. April 30, 2015
