Almost perfect! Recommend stitching the size on the sock on the 4.0 version. My wife and both wear apothecary socks, and it’s sometimes hard to mate socks after the wash.
At 50 years old I'm starting to appreciate a GOOD SOCK. These are soft yet you can tell their quite durable. They don't lose their shape in the wash and keep the right amount of elasticity and SNUG. Great colors!
