Great socks
Size: Medium, Color: Pink - 647
Well-made and comfortable to wear. Great for golf and other outdoor activities. Like them because they do not show above shoes.

These ACTUALLY stay put all day long - I was skeptical, but am so glad I took a chance on these
Size: Medium, Color: (014) Halo Gray / Halo Gray / Castlerock
I was so skeptical about whether these would stay on my feet all day without sliding down into my shoe - I’ve tried so many socks in the past with the silicone strip on the heel which failed.
I’ve owned these for a couple months now and they have never slipped down - they stay put all day! I love the variety of colors to choose from, and the value per pack is great since six pairs come per pack (I thought it was only three when I first purchased and was pleasantly surprised by the additional pairs). They also have perfect thickness - not too warm to wear during the summer months with sneakers; I live in a tropical climate, though, so I’m not sure how they will do in cooler climates. I’ve washed each pair once or twice and the color and quality of the silicone has stayed so far (knock on wood).
Overall: high recommend based on my experience so far!

No show but stays on
Size: Medium, Color: (014) Halo Gray / Halo Gray / Castlerock
I wear these socks daily. They truly don’t show with my workout shoes or with hey dudes. But the best thing about them is that they actually stay on your foot. I work out hard and I don’t ever have to pull them up. I do wish they were just a little bit thicker than they are, but they are definitely a product I will buy again.
