Incomparable

I've worn 'foot socks' for 40 plus years, I've never worn a sock that was so perfectly engineered as OS1st. While the comfort and technology are impressive, being I'm an avid golfer, the fit and 'stay' (meaning staying perfectly in place) are incomparable. I've worn just about every branded sock there is and I have finally discovered (and have been wearing a while now) the Very Best.

Active sock

I love these socks. They make such a big difference. I wear these especially to the gym. I will definitely continue to buy these socks.

Best I think I've ever bought

These are the best socks I have 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 will keep buying more.

Plenty of toe room

Comfortable because the toe box is wider and I can wriggle my toes.

Great socks

I love these socks. They are super comfortable. They provide the necessary cushion and support without being overly bulky.
