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.

The only socks I will buy
Size: 6-10, Color: Halo Gray/Assorted
These are hands down my favorite socks to wear with tennis shoes. Bought my original 6 pack in the store, liked them so much I went buy more and they were gone. These don't slip on your heel like most socks do. Come up high enough on the top of your foot to protect from tongue rubbing (I giggled when I wrote that) and they come in fun colors. Love they are ultra no show and provide padding but people can't see them with shoes on. Five stars!

Size: Medium, Color: Black
Amazing socks. Fits Amazing.
I tried to buy the six pack and it wasn’t the same. Thinner material. The 3 pack is great. Would buy again if it comes up.
