100% cotton socks

At long last I have found some socks that don't irritate me. In the past I have bought what I thought were 'cotton' socks only to find polyester added, or lumpy toe seams.
These socks are very comfortable and cosy. Thank you so much - I wish I had discovered your site much sooner.

These were purchased as a gift and they are so appreciated and loved. So difficult to get 100% cotton. Thanks 🙂

Absolutely love! I was looking for undyed GOTS organic cotton ankle socks and I found them thanks to Quinn. I'm definitely purchasing more since the fit is great and feel great on my feet. Thank you for what you do!

These are the softest socks I’ve ever worn! My feet do not sweat and they don’t slip down and ball up under my foot. Very comfortable and I can’t even feel the toe seam. They are expensive, but worth the money. I purchased ankle socks a couple of years ago and they are still holding up. Hate they were out of stock on a lot of items. Would love a drawer full!

My daughter is 17 months and this is the first time I’ve bought her socks outside of Amazon or other big box stores like Target. Won’t go back! The socks fit well, they are going to last much longer than her others, and we get compliments on how cute they are all the time!

Hi, My Name Is Melita.

I founded Q for Quinn to dress my son, who suffered from eczema. I was alarmed to find that around 90% of baby and kids' socks contained BPA and Parabens. This compelled me to seek a safer alternative.

Today, my small team and I strive to create healthy, comfortable organic cotton basics – gentle on our skin, planet and community.
