I wear Wrightsocks double layer every day. For running and everything else. I love Quarer size for Summer, crew for winter

I was hopeful the Running II socks would be the same as the ones I bought a year or two ago but, alas, they were not. They were higher on calf, and much tighter around the middle of the foot where an extra band is woven into the sock.
The ones I had earlier had two white stripes around the middle of the foot. I could not find them online - should have consulted with a customer representative before ordering ones with a green icon on top of foot.

I have some old wright white quarter socks running and just love them. I wanted to find them in black. I found that the company still exists and ordered 3 kinds of socks not sure which would suite my needs. The lightweight 8042.03 lo are good. The inner layer matches the outer layer. The quarter sock, midweight, the inner layer is bigger than the outer and bunches at the toe area. The run sock 3952.1501 are good when I tried them on, though I haven’t worn them yet The material feels rough and not as smooth as my old ones.

I was having blister issues with some other socks on long runs over 10 miles. These fixed that issue. Love them.

I have been wearing these socks for over 20 years, and they have never let me down. The double layer system really works! I have never had blisters, only a few sore spots on rare occasions. These socks keep my feet cool, too. I go running in some hot summers in the south central USA, and they hold up fine in the heat.
