Well worth it
Color: Black & Grey, Size: Large
Great fit and not too hot. I really like these socks. They are comfortable, keep my feet warm without overheating them and the material is holding up well. The colors are true and they are not too thick that my shoes fit tight.

Socks
Color: Blue & Green, Size: Medium
They are about what I expected for the price. Nice and warm, but they pill a lot and sit higher on my ankle than I'd like. Very cozy and comfy though. Great around the house, not really great for hiking though. Kinda thin after a few uses outdoors. Washable but not very durable.
