Alpinestars Thermal Tech Socks

Designed specifically for riding using a warming, breathable and moisture-wicking knit fabric to provide comfort inside Alpinestars boots.

The sole of the socks is combined with Nostatex fibers to provide antibacterial properties and to dissipate heat evenly throughout the sole to provide overall comfort


  • Warm and breathable moisture wicking knit fabric
  • Nostatex , silver yarn, sole for wicking moisture away from skin and giving an anti-bacterial, non odor, layer which conducts heat uniformly around the skin surface to reduce hot-spots
  • Ribbed design reduces bunching at the heel and ankle and increases riding comfort
  • Knee length design for ultimate coverage and comfort

Good Warmth with Minimal Bulk I bought these to replace the traditional hunting-style socks I used to wear in cold weather, which made my Alpinestars S-MX 5 boots fit a bit too snug for maximum comfort. These Alpinestars socks are the perfect solution, they offer me comparable warmth but are considerably thinner and give my feet more room to breathe. Like all compression-type socks they fit quite snugly on the calves, but the foot area is just right for my size 11 feet. Pricing is as good or better than many competitors' comparable socks, so I give these a thumbs up! January 19, 2016
Best riding socks Went for a 50 miles ride today with these socks. Simply amazing! Fit well and extremely comfortable. Reach up to my knees. Felt sense of well being in my lower legs long after I took them off. Highly recommend. December 13, 2015
Slightly Disappointed I have a few pairs of the summer weight Pro Coolmax socks, which I've really enjoyed, so when the temperatures started to drop I thought I'd give the winter pair a try. I'm not sure if I was epecting more warmth or what, but they really don't provide any significant amount of warmth. They're okay, but I would have a hard time even calling them good over any pair of ski/snowboard socks. Went with the same sizing as my summer socks, and they were a lot larger than I expected. Anyways, I still believe in the power of great socks, but these came up short in my book. May have to up the ante a little bit and spring for a nicer pair. December 2, 2015
Does what its supposed to do and good Snug Fit! Its a set of socks. What else is there to say?? They're warm, fit nice and snug with good compression on the calves. They fit right up to your knee. I am a size 11.5 shoe size and got the L/XL. Perfect fit. Alpinestars size charts are spot on. Make sure you know what your size is and use the size charts before ordering your own. I received mine as a present and didn't purchase it on Revzilla. however, I like them so much, i will be ordering a couple more pairs here on Revzilla. As always Revzilla is awesome selection, fast shipping and outstanding customer service. November 24, 2015
Decent socks, not super warm though Socks overall work well, but don't expect them to get the job done on their own. Once the temperatures get below 40 degrees your feet will get cold with these socks. I do have riding shoes which allow some air flow, so maybe if you don't have airflow it would be different. Overall they do help, and are extremely comfortable, just remember you'll need some sort of winter riding boots/shoes to combine with these socks to get into those less than 40 degree temperatures.

Nice socks Bought these socks for my cool/cold weather commutes here in n.e fla .i wore ski socks last year but they didnt come past the top of my boots.these do ( im 5' 10 ") they come up just below my knees . The foot has nice cushion/insulation without being to bulky. I havent worn them yet except for walking around the house .i wear a size 10.5 shoe so i bought the lg/xl.the fit is spot on October 6, 2015
just what i was looking for These socks work great , keeping your feet warm and legs also as they raise all the way just past the knees. Size was spot on , I'm an 8.5 shoe size and the small- medium fit perfectly. Would definitely recommend to anyone looking for something to keep their feet warm during cold weather or night riding. May 28, 2015
warm & comfortable Overall, the socks are great for cold weather riding. They are a bit long, as they almost cover my knees, but I found that it's better to cover too much of my legs than not enough, especially in cold weather. Nevertheless, they stay warm and dry. Great product. January 26, 2015
