Reading time: 4 minutes | Category: Care & Maintenance

Protect your investment in quality properly

High-quality merino wool socks are an investment in comfort and durability. With the right care, you can significantly extend the life of your Bolter socks while preserving all the valuable properties of merino wool. Here you will learn how to care for your socks properly.

The most important thing first: Merino wool is easier to care for than you think

Contrary to popular belief, merino wool is remarkably easy to care for. The wool's natural properties even support you in caring for it—it is self-cleaning and needs to be washed much less often than cotton or synthetic socks.

The golden rules of merino wool care

1. Less is more: Wash less frequently

The rule of thumb: Merino wool socks only need to be washed when they are genuinely dirty or when you have worn them for several days in a row.

Why this works:

Merino wool is naturally antibacterial
Odors are not retained
The fibers are self-cleaning
Air drying is often enough

Practical tip: Simply hang your socks up overnight to air out after wearing them. The next morning, they are often fresh again and ready for their next use.

2. The right washing technique

Step-by-step instructions:

Preparation:

Turn the socks inside out (protects the outer surface)
Place in a laundry bag (prevents felting)
Wash similar colors together

Washing cycle:

Temperature: Maximum 30°C (preferably cold water)
Program: Wool cycle or hand wash
Spin cycle: Lowest setting or switch it off completely
Duration: Short wash cycle (maximum 30 minutes)

The right detergent:

Use a special wool detergent
Never use fabric softener (it destroys the natural properties)
No bleach or stain removers
Prefer pH-neutral detergents

Hand washing—the gentlest method:

Pour lukewarm water (maximum 30°C) into a bowl
Add a small amount of wool detergent
Soak the socks (5–10 minutes)
Press gently (do not rub or wring!)
Use clear water to rinse
Gently squeeze between two towels

3. Drying: Patience pays off

The Do's:

Dry flat on a clean towel
Turn regularly for even drying
Well-ventilated place (not in a closed closet)
Room temperature is ideal
Shape them while the socks are still damp

The don'ts:

❌ Never put them in the tumble dryer
❌ Do not place over a radiator
❌ No direct sunlight
❌ Do not hang (this distorts the shape)
❌ Never wring or press hard

Special care for copper socks

Our copper socks require slightly adapted care:

Observe special considerations:

Copper threads are durable: The antibacterial effect remains intact
No special detergents needed
Same temperature as for pure merino wool
Effect is enhanced: Washing slightly roughens the copper surface, making it work even better

Storage: The key to longevity

Proper storage:

Store in a dry, well-ventilated place
Do not stack too tightly (wool needs air)
Prefer drawers or open shelves
Lavender sachets protect against moths
Cedar wood in the closet keeps pests away

Seasonal storage:

If you are storing thicker wool socks for the summer:

Wash and dry completely before storing
Pack in breathable cotton bags
Never in plastic bags (risk of mold)
Store in a cool, dry place

Repair and care for problem areas

Repair small holes:

Merino wool is easy to darn:

Obtain matching wool
Carefully weave with a darning needle
Do not pull too tightly
Work from the inside

Prevent felting:

Never wash too hot
Do not spin too vigorously
Do not rub while washing
Use special wool detergents

Remove pilling (small pills):

Carefully remove them with a wool comb
Never tear or cut them off
Prevention: Wash socks inside out

Avoid common care mistakes

Mistake #1: Washing too hot

Problem: Wool shrinks and felts Solution: Wash at a maximum of 30°C, preferably in cold water

Mistake #2: Using the wrong detergent

Problem: Destroys the natural properties Solution: Use only special wool detergent

Mistake #3: Washing too often

Problem: Unnecessary wear Solution: Wash only when necessary, air out more often

Error #4: Improper drying

Problem: Distorted shape, material damage Solution: Always dry flat

When is professional cleaning advisable?

In rare cases, professional cleaning may be necessary:

For stubborn stains
After prolonged storage
In case of heavy soiling
When the socks have lost their shape

Important: Choose a cleaner experienced in wool care!

Maximize the lifespan of your socks

Rotation is the key:

Use at least 3–4 pairs in rotation
Let socks "rest" for 24 hours between wears
Different thicknesses for different shoes
Spare pairs for travel and sports

Preventive measures:

Keep feet dry: Sweaty feet put strain on the material
Proper shoe size: Shoes that are too tight cause friction
Change shoes regularly: Let shoes air out for 24 hours
Use insoles: Reduces direct contact and wear

Seasonal care tips

Spring and summer:

Air out thinner socks more often
At high temperatures: rinse with cold water in the evening
Pay more attention to odor development
Easier care because of less sweat

Autumn and winter:

Thicker socks need to be washed less often
Dry especially thoroughly after hikes
Watch out for salt residue from winter shoes
Remove snow moisture immediately
