These have quickly become mine and my mom's favorite socks. We wear them with tennis shoes, Hey Dudes, and more. The fabric is incredibly soft and comfortable, they do not budge/fall in my shoe, and are extremely well made. I have become so attached to these socks, that I no longer want any other brand.

The perfect sock!

Size: 6-10, Color: Halo Gray/Assorted

The only socks that I can wear with my hey dudes. They stay on my ankles and never slid down into the shoe. I will forever order these as long as they are available. They are comfy too!

Good option, especially in warmer weather

Size: 6-10, Color: Black

High quality socks and very durable. Nice touch adding the grip on the back of the ankle so the sock stays up. Size is a true fit to the size of your foot as well.

Love these socks!

Size: 6-10, Color: White

Comfortable, no show, and most importantly The Do No Slip!!!! I keep coming back to add to my supply because they have become the only sock I wear. I’ve been using them for a couple years now and they hold to great to washing, bleaching and the dryer. Highly recommended.
