these are definitely socks. I can confirm they're fantastic socks though. They're soft, comfy, breathe well enough, and have a minimal aesthetic.
These are sturdy and warm but not too thick & great for year round riding
The socks are thin but surprisingly warm. I wish that manufacturers of cycling clothing would advertise products as being rated for a certain temperature range. These I would put in the 50°F and up category. I wore them on a slightly chilly ride and thought my ties would be cold but they were great. They wash and wear very well. Highly recommend.
Great, warm and good looking.
