Perfect minimal running sock I love these socks! I have worn them for running anywhere from 3-6 miles at a time with no issues, but if you want cushion/extra support don't buy these! They are extremely thin and light. February 3, 2015
Help my neuropathy My socks were a perfect fit! Fit just like a glove. I have never had a sock the fit so well. It took me a few days to get use to the different texture. After that I had forgotten I had them on. With the regulated body heat it's keeping my neuropathy at bay. Thanks February 15, 2014
Enjoy the trail, your feet will stay dry These are the perfect running sock - a very comfortable fit and your feet will stay dry even through a run on a wet west coast day! Love these socks! December 2, 2013
Great running socks My daughter uses these socks when she races cross-country and loves them. No blisters ever, not too warm for running, but keep your feet warm in cool fall weather. October 18, 2013
got me through half marathon training and the race I wore these socks while training for a half marathon. When wearing them I never once got a blister and my feet felt comfortable and supported! The one week i didn't wear these was the week I got a blister. I need to buy another pair as I was in a big panic when I thought I had lost them before the actual race. Thanks for producing such a fabulous product Icebreaker!! May 23, 2012
very lightweight These socks are very lightweight and smooth, which means they move against the inside of my shoe easily and don't rub on my skin instead. It took me a minute to figure out there is a left and right sock, and the fabric around the heel doesn't fit as smoothly as I'd like (maybe because I have very narrow heels?) but I smoothed it out in the end and had a comfortable run in them after all.

No cushion Multisport Micro series comes with Cushion style but no Cushion style in Run Micro series. Why? They are comfortably rightly fit just like a second skin. I always wear size S in socks but after one cold machine washed and laid dry, they were shrunk a little bit and now they are marginally fit. So I'm actually wondering that if I should give size M a try... Price is slightly different between Run Ultralite Micro and Multisport Ultralite Micro but the material are exactly the same: 55% merino wool, 43% nylon, 2% elastane. Run Ultralite Micro indicates the right/left sock with logo but Multisport Ultralite Micro does not July 21, 2013
