Good boot sock I bought these top foot under some new books that were taller than I had before. Just got back from a 4 day trip wearing these and am pleased with the performance. They come up to my knee to protect me from my boot, were very comfortable, and they're not too hot. September 21, 2015
Comfortable These socks are very soft and comfortable. There are no hot spots and contrary to logic they actually keep your feet dry and cool. Its not what you expect from a long pair of socks. August 31, 2015
Very good boot sock. Very happy with the socks. Fit well, durable, great price. August 11, 2015
Nice fit great over the calf protection form SIDI boot sides August 10, 2015
Love these on hot days I am very happy that I purchased these up use during the summer. I used to just use whatever longer socks that I had when I went out riding, and my feet would get very sweaty. I also have vented boots, but the socks were the problem. These allow plenty of air through. I also haven't been getting sores on my feet like I usually do when I break in a new pair. Sadly they don't look new after just a few washes. There isn't anything wrong with them and they still perform just as well. They just look well used after a short time. August 7, 2015
Great Warm Weather Socks Never underestimate the value of comfy socks!!! I needed a proper replacement for the soccer socks that I had been wearing previously, and these, at this price point seemed like a good choice. Very happy with them so far, they're very soft and comfortable, and far easier to get on and off than my previous socks. I wear the TRQ Gore-Tex boots and the combo couldn't be better. I'm a size 9.5 and the Large fits well. If you need to get to the next $100 mark on your order, or have some 'zilla cash laying around, these are definitely worth the small investment. Will look to get the thermal pair as well for fall/winter riding. July 29, 2015
Nice knee hi socks, stylish, functional, well made. Overall a really good product and there aren't too many out there with alpine stars quality style and durability. Eventually the colors fade and the elasticity goes south but that's after months of constant use. An inexpensive sock that holds up well and looks cool without being austentatious. July 13, 2015
Excellent socks! These are perfect for high socks. Now, if AS would only take their obnoxious logos off their jackets, I'd buy one :) June 29, 2015

Brigham M: That should work. I wear a 10.5 shoe size and wear the LG/XL socks. Wore them for a 6 hour race day last weekend and was very pleased with fit and breathability.
I wish Alpinestars would put some sort of sizing chart for these on their site.

Tom C: In my opinion, yes. I wear a 7 boot, 7.5 shoe and they're small enough to fit well, but they'll easily stretch for a 8.5 size. May 25, 2014

Noah L asked: The size chart used does not apply to this product. What size range is the SM/MED and the LG/XL? May 26, 2015
Answer this · Send to friends Good question? Yes (0) No (0)
Noah L: Well I bought them and really like them so I'm here to answer my own question. According to THE SIZE CHART ON THE BACK! (Thanks for the help Revzilla!)
S-M fits (EU) 36-41 / (US) 4.5-8.5
L-XL fits (EU 42-48 / (US) 9-14
I usually wear a 10 and the L-XL fit perfect. Great warm weather sock. Nice and thin, no bunching, no issues. They are knee high so I fold them down a little.

Paul O: I purchased the LG/XL and wear a size 13 shoe. Normally socks are on the short side for me, these fit comfortably, so I would say they run a little large based on my experience. Jun 8, 2015

Pete W: They are really nice socks et would also be good for Autumn weather ... I would wear them over here in winter (in a boot, not shoe) but our winters in New Zealand are pretty mild compared to some with temps around 8 to13 degrees celcius. Mar 10, 2014
