The best no show socks
The only no show socks I have ever found that do not slide down. These are very comfortable and the extra tab on the back provides comfort by keeping shoes from rubbing the back of your foot. The top of the sock also comes up high enough to cushion the top of your foot all while still remaining hidden while wearing tennis shoes or even with my hey dudes.

Great product and service after disappointment
Flavor Name: Traditional, Size: 4 Ounce (Pack of 1)
Ive tried a few different brands of biltong and made my own. I have to say that this wasn't my favorite. Believe me, i wanted to like it. The taste was sour and most of the bag was pulverized shreds. :( I did find that letting a bit airdry in a bowl made it a little more palatable, but honestly it'sjust sitting in my fridge still, where normally I'd have eaten the whole bag in a day or so. I will say that there was a decent amount for the price. The texture and cut were good on the whole pieces. Also, some of the bites left a weird coating and nasty taste on my tongue, like baking soda or something, but definitely an off taste.
I had my own beef jerky store for several years, so I'm a connoisseur, but no snob.
-----update 8/13/2019-------
I contacted customer service via the email on the bag and got a response. They sent me a new bag and here is the email I sent them back. Very happy now.
....The biltong showed up last Thursday! I'm sorry i kept forgetting to email you.
It is delicious. It's night and day difference between the bag I got through Amazon originally.
This bag was pristine and the taste is spot on. Every piece is a perfect slice, no shreds or fluff. Dark, rich brown color, not hay colored like the old bag. I really think that the other bag got very hot or something and out the taste off.
Thank you so much. Now I know that if I am in the mood for biltong, Ayoba-yo is a good choice.
Thanks for the customer service as well.....

Ayoba-Yo Traditional Beef Biltong
Flavor Name: Traditional, Size: 4 Ounce (Pack of 1)
I have been lucky to visit South Africa a few times in my life. What is not lucky is coming home to the United States and craving biltong. Biltong is a magical, sugar-free, barely processed jerky and once you try it, you will never want to eat American beef jerky again. Biltong made in South Africa cannot be imported to the States, which is probably the saddest thing ever. I have searched for the perfect recreation of what I have eaten while road tripping through the Karoo, and I haven't found anything that can match it. Until I got this Ayoba-Yo Biltong delivered to my door yesterday. My search is over. Ayoba-Yo is a match to the biltong in my memories. The meat is sliced thin and perfect for snacking. It is fresh, doesn't contain any gross preservatives, and the flavors are the perfect traditional blend. Try this biltong and make the switch, you won't be disappointed!
