'Max' socks feature a thick terry-loop interior that provides soft cushioning underfoot while helping to trap warm air for insulation. Combined with the natural breathability of Australian-grown merino wool, they help keep your feet comfortable across a wide range of conditions.
The addition of nylon increases durability, helping the socks stand up to the demands of long days on your feet, without compromising comfort.
Whether you're heading onto the hiking trail, or heading out to work, 'Max' is designed to deliver lasting warmth, comfort and durability.

Why Merino Wool?
We choose premium Australian-grown merino wool because it's naturally breathable, helps regulate temperature and manages moisture better than synthetic fibres. That means your feet stay comfortable whether you're facing cold winter conditions or warmer summer weather.
By combining merino wool with nylon, we're able to create a sock that balances natural comfort with the durability needed for extended periods on your feet.

Frequently Asked Questions
How thick are 'Max' socks?
'Max' is one of our thickest socks, featuring full terry-loop cushioning throughout. They're designed for warmth, comfort and durability inside hiking boots, work boots, and shorter length gumboots.
Are 'Max' socks suitable for steel-toe work boots?
Yes. Their thick cushioning makes them an excellent choice for steel-toe work boots, provided your boots fit correctly.
Can I wear them all year round?
Yes. While 'Max' is one of our warmest socks, the natural properties of merino wool help regulate temperature, making 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.
Are 'Max' socks itchy?
No. Australian-grown 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 thick, full-cushioned sock without synthetic fibres, you may wish to consider our Merino + Hemp 'Wombat' socks.
Where are they made?
Every pair is knitted at our factory in Crookwell, Australia.
Why is XL more expensive than the other sizes?
The pricing is higher than our other 'Max' 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.
