I really like this sock. It comes in different heights and colors, and is compressive around the ankle.

All Swiftwick socks are long wearing. These have a bit more paddingthickness under the foot that the Aspire model which I prefer, but the Aspire is very good also.

I wear the Merino model in cold weather , They are warm and thin enough to fit in my shoes.

Great socks.
