Pretty nice socks
I wouldn't call them no show, but pretty close. Also, as others have mentioned, they run big. I wear a size 12 shoe and got the L/XL socks and they were a tiny bit big. They are now perfect after a couple washes. If I had to pick my ideal setup I would choose Merino over Synthetic. Although, at the steep and cheap price, they are a great deal that I would purchase again.
