Great no shows for people with larger feet
Size: Large, Color: (001) Black / Black / Castlerock
Some of my favorite socks!! Great quality, fit, and material. I love that they don't slip down in my shoes, especially considering I have larger feet. I also love that Under Armour offers larger sizes in their socks considering everyone in our household has much larger feet than others.

Best liner socks EVER
Size: Medium, Color: (348) Silica Green / Silica Green / Hydro Green
I have them in every color and used to get them from Sams, but they stopped selling them and I was lucky to find them on Amazon. Got all colors again. They stay, it's all I'm gonna say! And don't show in any of my tennis shoes. Absolutely love them and wear them until they get holes. They last a LONG time too. They're on the thin side and my foot loves them because they tend to get hot. There's no shrinking, they wash great with exception of the white ones I couldn't manage to keep white - they turned a bit greyish.

Well-made and comfortable to wear. Great for golf and other outdoor activities. Like them because they do not show above shoes.
