Lightweight and very comfortable. Does not bunch up, fits very well
Bought these cause they were recommended to me by a friend to wear for a 26.2 mile marathon. They did well up until mile 10-11 hot spots started and blisters soon after. Maybe was the shoes or other factors? Look good feel great but I still did get blisters. Maybe I didn’t use em right? It’s a sock out it on and go? Willing to give em another shot.
Hi Charlie,
We're sorry to hear that the Merino CoolMesh didn't perform as well as you were expecting. From your description it sounds like the socks were working as intended until that 10-11 mile mark. It is possible that if you're shoes became a bit looser as you were running that could have contributed to the problem. It is also possible that if you were using another form of blister protecting like Body Glide gel or a Mole Skin patch they could have been a factor as well. Body Glide and other gels while they work in tandem with Wrightsock short term the gel greatly diminishes Wrightsocks ability to wick away moisture which can lead to added friction to an area rather than lessen.

Wrightsock Customer Service
It’s been 3 weeks since I ordered(#56160) two pairs and package probably was stolen or lost. Tracking stopped 2 weeks ago. I sent an email to wrighsocks and someone named Kimberly replied something like “contact post office in your country”. I guess I’m on my own
great deal
I wish Wrightsock would have a filter for thickness: light, medium, heavy. These were about dress sock thickness and I needed a medium thickness. Not worth the trouble of returning them. Otherwise...very well made, comfortable socks.
