The Mid Weight Merino Crew Socks are an epic all round sock for all weather conditions - warm or cold. Hike in them, run in them, ride in them, or just wear them for everyday comfort and enjoy the many benefits of natural Merino wool socks.

These multi-purpose socks deliver all the comfort of natural Merino wool socks in our new longer Crew length. They’ve been designed with a unique Merino-rich blend has been specially formulated for blister-prevention. The temperature regulating and moisture wicking benefits of the superfine Merino help keep your feet warm, comfortable and ‘odour resistant’ without overheating.  The cuff prevents sock ‘slippage’ so you’ll avoid any shoe rub, there’s extra padding in all the places you need it, and thinner, ventilated panels where temperature regulation is more important.

They’ll keep your feet warm in the cold, and stay comfortable if they get wet. They feel silky smooth and comfortable straight out of the pack.

Perfect for hiking in a low cut boot, running, riding or just for day to day wear.

Designed to be a ‘crew’ length.  Slightly longer than the Multi-sports socks.

Made with anti-itch 80% superfine Australian Merino and 20% nylon for stretch and support.

Best mountain biking socks!

These socks are so comfy and warm! I cycle a lot, both on the road and on the trails and these are my favourite socks for on the bike. My partner has a pair too and he loves them as well. He tries to steal mine when his are dirty but I fiercely defend them!! I can highly recommend these socks! :)

My feet love them!

I just raced 640km in these socks in 5 days and didn't get a single blister. Perfect.I just raced 640km in these socks in 5 days and didn't get a single blister. Perfect.


Have worn many merino socks over the years and these are hands down, the best! Have purchase 4 pairs now and will get more as needed!


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.
