Quality, comfort and support.
Size: Medium, Color: Deep Sea/Breaker Blue/Electro Pink
These socks are the bomb! If you are athletic or on your feet for extended periods these great looking, well made socks are constructed to offer just the right amount of compression and support. The toe is soft and thick. I will order these again and again. Hopefully Amazon will add even more color choices on the future.

Best socks
Size: Medium, Color: Pink Elixir Assorted
Everyone got socks in their stockings this year. But no one was complaining. They weren't thin like some socks. But not super thick either. Just right. I even bought a pair for myself. No regrets. Will definitely buy again.

Love it it was perfect for what I needed it for. Good quality!
Size: 4 Panel, Color: Black
It like a very dark chocolate brown/black. What I liked most about it is that you just pull it out of the box take the long plastic film off of it and it's ready to go. It has protective feet on the bottom. It's very attractive and it was so easy. It's so nice when you have a product you don't have to assemble.
