The perfect sock!

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.
