Comfy socks

These socks are very cosy and cushy. I love that there are new colours out now - will be getting some more. Thanks io :)

Melinda Obern (Sydney, AU)
Awesome Socks!

I'm an outdoor PT, and I need my socks to be warm, supportive and comfortable for hours of being on my feet in all sorts of conditions. These definitely do that. I'll be ordering more!

Jodie (Sydney, AU)
So comfy!

I had been waiting for ioMerino to bring out running socks, and here they are!! I walk in them and run in them. I wore them running in 2 degrees celcius. Parts of me were freezing, but not my feet!! I also wear them in warm weather and they are very comfortable. They are softer and cushier than I thought, which is lovely. And as with all the other ioMerino stuff, they don't smell, so you can wear them multiple days in a row without offending anyone ;) Great for travelling! Love these and highly recommend!

Helene (Sydney, AU)
Perfect warm woolly short socks

Wore these today out and about town in the cold, had my new barefoot boots on and my feet were cosy warm and really comfortable. The socks don't slide down like others I've had, and they give my feet a nice cushiony soft landing as I walk.

Sharron (Melbourne, AU)
The best socks around.

Having searched hi and low for something like this, so glad to see these come up. They are incredibly comfortable and fit beautifully (size 9 women's and purchased medium). Hopefully more colours in the future😁

Fabric Guide

While Merino is an amazing natural fibre, not all Merino fabrics are created equal. At ioMerino, we make our own fabrics, using only the best quality fibres, and to very specific specifications that make the most of the natural benefits of Merino. All of them are 'Merino rich’. No cheap blends passed off as Merino. No cheaper scratchy fibres or synthetic substitutes to save money. No unethical production. And each fabric is made for a specific purpose. So if you see something with a small amount of elastase or nylon added, you can be sure it absolutely needs to be there to enhance the natural stretch and durability. 

It took every bit of our 140 years of experience in the wool industry to perfect our fabrics, but we think you’ll agree the end result was more than worth the effort.

Ethically Made. Ethically Sourced. Perfectly Natural.
