Good socks, good price! 🧦
This is my first pair of merino wool socks. The price is great for someone that doesn’t know if they’ll like merino socks and doesn’t want to drop $20+. With that being said I like them a lot and will buy more and try different brands.
Thin socks
Thin socks and has static shock wearing around the house with just the socks on. I guess good for minimal travel since it will probably dry quick after washing.
