Everyone suffers from it at some point in their lives (some more than others), and no one is talking about it: smelly feet. It’s the kind of stench that can leak your shoes. It’s plain embarrassing. Other than washing your feet every hour, you can control your foot odor by choosing the right pair of socks. And you know which yarn makes the best socks for stinky feet? That’s right Merino wool!

Before determining the best socks for stinky feet, we must understand why your feet stink and how our favorite performance apparel – Merino wool – helps fight odors.

Note: We’ll be focusing mostly on lighter socks, as they are best for smelly feet. If you are looking for heavyweight merino wool socks, you can read our full review here.

Why Do Your Feet Stink?

Stinky Feet & Shoes

Pungent foot odor may just sound like a passing issue. Still, it’s a persistent, debilitating, and embarrassing problem for many of us.

So, why exactly do your feet smell so bad after walking around all day? Bacteria, of course!

Tiny microorganisms all over your body thrive in moist & dark environments. As you sweat, these bacteria munch on the oils and proteins in your secretions, along with your dead skin cells. To be frank, they are just snacking away at your bodily juices.

It’s the organic acid byproducts of these bacteria that cause you to smell. They are living off of your sweat, emitting a foul-smelling organic acid, and growing their colony.

If that’s the case, why doesn’t your whole body smell?

Well, your feet have nearly a quarter-million sweat glands, which is much more than any other part of your body. The microorganisms have better ‘nutrition’ and living conditions inside your socks than they do on your hands.

For your average person, these bacterial emissions are the cause of smelly feet. But for others who suffer from severe foot odor, there is an additional culprit. Nearly 15% of feet contain the bacteria – Kyetococcus sedentarius – that produces volatile organic sulfur stench. It basically smells like someone is peeling eggs inside a pile of old gym clothes.

So, as we mentioned before, the two main ways to control this odor-causing bacteria are thoroughly washing your feet and creating an unsuitable environment for the bacteria to thrive. Again, we earnestly hope you’re washing your feet, so we are more focused on the latter, which you can achieve by wearing the right socks.

How Does Merino Wool Prevent Odors?

In addition to being thermoregulating, super comfortable, and high-performing, Merino wool is actually an odor-proof fabric. But, it’s not as simple as you think.

The traditional assumption is that Merino wool controls odors by providing a harsh environment for bacteria. Makes sense, right? If bacteria couldn’t survive, they couldn’t eat your foot juices, thus, not releasing any smelly byproducts.

Well, that’s not exactly the case.

Wool tends to have the same amount of bacterial volume after use compared with synthetic materials. But it’s how the fabric traps the stench that makes it odor-resistant.

If you didn’t know already, wool has significant water absorption properties due to its hydrophilic nature. It can retain up to 30% of its weight in water before actually feeling wet. Now, the bacteria that live within the fabric are still munching on your sweat proteins. But, their smelly byproducts become trapped in the fabric’s water moisture content, not within the material itself.

The same cannot be said for other sock materials like polyester. Their quick-dry nature allows organic acid odors and sulfur smells to adhere to the fabric’s surface. With purely synthetic materials, your socks don’t trap the odors and release them until they reach the nostrils of an unsuspecting victim.

The moral of the story: stick with socks made from Merino wool or Merino wool blends.
