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.

Good value & taste.

I've bought these beef sticks several times & they're great. I'm not particularly fond of teriyaki flavor so I'll go back to the original. They're a good snack with cheese.
