Do Merino Wool Socks Shrink?

Yes, Merino wool socks can get shrink. But only if you don't wash them right. Wool is natural, like cotton. It doesn't like heat or lots of movement. And it doesn't like big temperature changes. If you use hot water. Or put them in a hot dryer. The wool fibres can squeeze together. This makes the sock smaller and harder. But don't worry! They don't have to shrink. If you wash them the right way. Your wool socks can stay the same size. And they'll feel good for a long time.

Why Merino Wool Shrinks

Do you know how wool gets smaller? It's called felting. Imagine tiny parts on the wool. When it gets hot and moves a lot. These tiny parts open up and get stuck together. This makes the wool tighter, and the sock gets smaller. That's why some wool-mix socks shrink less. Merino wool feels extra soft.  But that means it's also more delicate. So you really need to wash it gently. And dry it the right way.  

How to Wash Merino Wool Socks (the Right Way)

  • Read the Care Label: Not all Merino socks are the same. Some brands wash the wool first. Or they treat it so you can use a machine. But other socks need you to be more careful. So always look at the tag first. The tag will tell you how to wash them. That way, you won't make them shrink.

  • Use Cold Water: Want to keep your socks the right size? Wash them in cool water. Never use hot water! Hot water is the big reason socks get tiny and hard.

  • Choose a Gentle Cycle: Using a washing machine? Choose the gentle or wool setting. Even better? Wash them by hand. This is the safest way to wash them. 

  • Use Wool-Friendly Detergent: Strong soaps can hurt the wool in your socks. They wash away the natural stuff that keeps them soft. This can make the wool weak. So use a gentle soap instead.

Can You Put Merino Wool Socks in the Dryer?

Can you put them in the dryer? Yes, but it's not a good idea. If you want them to stay the same size and feel just as soft. Air-drying is the best way. Lay your socks flat on a clean towel or put them on a drying rack. Let them dry all by themselves. Don't hang them up. Hanging can make them stretch out. If you need to use a dryer fast, then use the lowest heat you can. Take them out when they're still a little wet. Then let them finish drying in the air.

How to Keep Merino Wool Socks Like New

How long your socks last depends on two things. First, how good the wool is. Second, how the sock is made. For example, men's merino wool socks for hiking are strong. They have extra stuff on the heels and toes. They might also have stretchy threads like nylon. This makes them last longer. So you get the good stuff from wool. And the strength of other materials. 

But super-thin socks made only of wool. They might feel great. But they might wear out faster. Also, some people think the length of the socks matters in shrinking, while it's not true. Whether you prefer Merino wool ankle socks for workouts or Merino wool crew socks for hiking, the care instructions remain the same. Here are some tips to make your wool socks look new, like you purchased them a few hours ago.


  • Rotate Your Pairs: Give your socks a break sometimes. Don't wear the same pair every day. This helps them last longer. Especially the parts that rub a lot. Like your heel and your toes.

  • Wash Less Often:  The good news about Merino wool socks is that they don't smell easily. So you don't have to wash them all the time. If they don't look dirty or if they're not super sweaty. You can wear them more than once.

  • Store Them Properly: Don't squish your socks in drawers that can make them stretch out. Instead, roll them up nicely or fold them gently. Then keep them where air can get to them. This helps them stay in good shape.
