Actually stay on your foot!
Gosh, these are the best socks that actually stay put and don’t slip off your heel! Found these on vacay when my other sport socks wouldn’t stay put. Just note, they are marked L & R for a perfect fit. Super comfy with the extra padding :).

Most comfortable socks!
Great socks, hubby only wears them! They’re expensive, so I’ll have to budget to buy a pair!

Best think I’ve ever bought on Amazon
These are the best socks I’ve ever had. They fit like a glove, even telling me R & L. Easy to wash, put on. Look wonderful. Stay up where they belong. I totally love them and keep buying more.

Low quality and thickness / Updated
I first bought OS1st socks from a Good Feet store locally(40 minute drive), which is why I proceeded to purchase more of them online. After receiving these online socks, they are not the same quality. The material is very thin and nowhere near the thickness of my original socks. I’m really disappointed in this purchase and I wouldn’t recommend them at this time.After receiving a message from the seller, I’m changing my rating from a one star to a five star. I was unaware that there were different varieties of these socks. Please see attached photo. These socks are what they call “Active Comfort”,and are much thinner material wise. The socks that I expected are called “Wellness Performance” socks and are thicker material wise. The seller has offered to send me the socks that I was expecting.Not only am I receiving the socks I expected, the customer service department was fantastic. Thank you.

These socks are great if you’re prone to getting blisters. They’re very comfortable fitting like a glove

Haven’t found any downsides yet.
My local shoe store uses OS 1 as their try on shoe sock. It was so good I bought some. They have many types. They label left and right feet. They seem well made. I am happy and will buy more.
