No Show Socks Men - Loafer Low Cut Non-Slip Invisible Liner Casual Socks for Boat Shoes(6 Pairs)

So I have `Assorted 01 - $9.99` which don't slip off, but after a dozen or so wears, it develops holes. So I was excited to see the updated `Color 04 - $13.99` model, which is thicker around the toe area. However, about 5 out of 10 pairs of the newer model, slip off my feet. They do feel more durable though. I wanted to really like them, but it's hard for me to recommend them. Also, the Color 04, doesn't have anti-slip bottom, which I kinda liked in the Assorted 01.
