For trail runners there's no better sock than the Thorlo AOQU. Specifically designed for intense outdoor sports including obstacle courses, mountain running, mud runs, endurance races, boot camps and biking, its quarter height with a reinforced top  and moisture-wicking fibers help keep dirt out, feet dry, and blisters away. Compression-grade ankle and arch support protects plantar fascia, keeps socks in place, and helps fight fatigue by promoting circulation. Light density padding in ball and heel areas protect you were you need it, without the bulk. The OAQU Unisex Trail Running sock is proudly made in the USA.

Bought a pair of these

Bought a pair of these two years ago and really like the thickness and fit. So please to find them available here.

Good for running

My son l8kes them. He runs x-country and says they are soft and cushiony.

Comfy, but a bit tight

I've been wearing Thorlos for years. This is the first style that didn't really blow me away. I usually wear size 10 1/2 shoes, and while my other Thorlos for that size fit perfectly, these run a little small/tight, although after a few washings I'm getting used to them. Not sure what to recommend to others in my size range. However, once they are on, the bottoms are comfortable and a nice weight for general walking around. The patch-like color is quirky, but I'm getting used to that, too.

Thorlo OAQU socks

This sock has arch support, but I need additional heel cushioning, without toe cushioning. Plantar Fascitis, for me, is 99%in the heel. Adding toe cushioning causes tightness where it is not warranted or wanted.

I gave you a 4

I gave you a 4 because one pair has a defective right heel. I play tournament softball and after only two games I noticed the defect. In a past life I was active in marathons and triathlons and wore Thorlo socks. Not sure what happened with this pair ….
