Good socks for leisurely activities
Nice socks to wear to bed and walking around, but not ideal for running. They tend to rub toes the wrong way and there are a lot of extra threads in the entire interior that can be a bit annoying, but nice and fluffy to keep my feet warm while sleeping and walking in cold weather. They wouod probably be fine for cycling in cold weather also.
Pretty, lightweight hiking socks
They're lighter weight than I expected, but very pretty and have reasonable cushioning.
