Part of our Heritage Collection, 'Otto' socks are knitted in our Aussie factory using 75% Australian-grown merino wool and 25% nylon. Their medium-weight ribbed construction provides reliable comfort without the bulk of a full-cushioned sock, making them one of our most versatile styles.
Whether you're working, walking or enjoying the outdoors, 'Otto' is designed to keep your feet comfortable throughout the day.
Why You'll Love Them

Designed for Everyday Versatility
'Otto' is the ideal choice if you prefer a medium-weight sock that can comfortably handle a wide variety of activities.
Its ribbed construction provides gentle support while the medium-weight knit offers more cushioning than a lightweight dress sock without the extra bulk of our thick full-cushioned styles.

Whether you're on the farm, on the worksite, heading into town or enjoying a weekend walk, 'Otto' is designed to deliver reliable everyday comfort.

Frequently Asked Questions
How thick are 'Otto' socks?
'Otto' is a medium-weight sock that provides an excellent balance between warmth, cushioning and breathability. It offers more cushioning than a lightweight dress sock without the bulk of our thick full-cushioned work socks.
What does ribbed mean?
The ribbed construction allows the sock to comfortably mould to the shape of your foot, providing a close, supportive fit throughout the day.
Are they suitable for work boots?
Yes. 'Otto' socks are designed for everyday use in snug-fitted lace up work boots and hiking boots and a wide range of other footwear. If you have looser fitting work boots consider our 'Max' thick, full-cushioned merino work socks.
Are they suitable for hiking?
Yes. Many customers wear 'Otto' socks for hiking, walking and other outdoor activities where a medium-weight sock is preferred.
Can I wear them all year round?
Yes. Their medium-weight construction, combined with the natural properties of Australian-grown merino wool, makes them comfortable throughout the year.
Can they go in the dryer?
No. To avoid shrinkage, we recommend a cold, gentle machine wash and line-drying away from a heat source. For more information, see our Care & Storage guide.
Will they itch?
No. Australian-grown quality merino wool is naturally soft and comfortable for all-day wear.
Why do you use nylon?
Nylon adds strength and durability, helping the socks withstand everyday wear while retaining the comfort and performance of merino wool.
If you're looking for a synthetic-free medium thickness ribbed sock, you may wish to consider our Merino + Hemp 'Echidna' socks.
Where are 'Otto' socks made?
Every pair is made at our factory in Crookwell, Australia.
Why is XL more expensive than the other sizes?
The pricing is higher than our other 'Otto' sizes to account for the additional yarn used to make our XL socks.

Care Instructions
Care Instructions
Due to the natural crimp in wool fibers, our socks will shrink up to 10% when first washed. We have allowed for this shrinkage with our sizing, which is why your new socks may look a little bigger than expected when they arrive.
Caring properly for your Lindner products will ensure they last for years to come.
We’ve created a handy how-to guide below, to help you care for our socks, accessories and apparel.
For further tips and information about caring for wool products, please visit the Woolmark website.
In addition to properly caring for your socks, there are a few key reasons that socks wear out quickly. To learn more see Reasons Why Socks Wear Out.
WASHING & DRYING
MERINO SOCKS

WASHING
Wash socks separately
To help care for your merino socks, they should be washed separately, or in a hosiery and lingerie wash bag so they do not catch on other garments.
Use a cold, short, gentle wash cycle
For all socks, excluding our 100% pure merino 'Stringybark'* socks, we recommend a cold machine wash on a wool or woollens cycle setting, using a mild wool detergent. Shorter cycles are better as some front loaders have long cycles and may even heat their own water, so beware it doesn’t get too hot.
Use a low spin speed (RPM)
A high washing machine spin rate (RPM) can also cause the wool to shrink because the high speed causes friction and agitation that interlocks the wool fibres - a process called felting. To prevent shrinkage of your socks, we recommend using a low spin speed, ideally 600 RPM or less.
For more machine-washing tips see our video below.
Alternatively, our merino socks can be hand washed using a gentle laundry soap. Our Stringybark socks should be washed using a cold hand wash only, as heat will cause shrinkage.
*Our Stringybark socks are currently unavailable.
DRYING
Tumble dryers and dry cleaning should be avoided, as they will cause your socks to shrink. Air drying in the shade is best, as direct, intense sunshine or drying close to heaters can also shrink the wool.
If you have accidentally shrunk your socks, never fear, you can try to stretch them out whilst they are wet.
MERINO APPAREL AND ACCESSORIES

WASHING
When washing merino beanies, scarves, and tees and rugby tops we recommend following the same instructions for washing merino socks, as listed above.
DRYING
As with our merino socks, tumble dryers and dry cleaning should be avoided as they will cause your merino beanies, scarves, tees and rugby tops to shrink.
Air drying in the shade on a flat surface is best, as drying on a clothesline or hanger can cause wool products to stretch and become misshapen. For best results, we recommend laying them on a clean, light or white lint-free towel.
MERINO AND ALPACA BLEND SOCKS AND ALPACA SCARVES

WASHING
As alpaca fleece is a hair fiber, our alpaca farmers recommend the best way to care for our local merino and alpaca blend and local alpaca products is to hand wash them in shampoo (any hair shampoo will do, as long as it doesn’t have color pigments).
DRYING
Tumble dryers and dry cleaning should be avoided when drying our merino and alpaca blend products to avoid shrinkage. As with our merino products, air drying in the shade is best.
