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!

Amazing socks but false advertising. They changed them.
Size: Large, Color: Black (6-pairs)
Okay well I have 4 stars because these are the best socks ever, infact, I threw out all my other socks and switched to just these. No show and they never slip. THE PROBLEM NOW, all the pairs I ordered before had a white symbol, and every time I buy more they have the grey and they are not as low show as my others… I wanted to simplify life and have all the same kind, no matching of colors or slightly different shape, but 4 times now I’ve ordered white symbol and gotten thicker longer ones with gray symbols. I’m considering switching all of my socks to the gray…. But the white symbol ones are way better, they don’t show with hey dudes on and gray symbol ones do now. I’m at a loss. Can someone tell me where to buy 100 pairs of white symbol so I never need to buy another sock again in my life?
