What Sock Brands Won’t Tell You

What Sock Brands Won’t Tell You

Regular socks can be dirtier than a TOILET

  • Feet have about 250,000 sweat glands.
  • Feet can sweat up to half a pint a day.
  • This sweat is a breeding ground for bacteria.
  • Shoes have around 421,000 bacteria.
  • The bad smell is due to odor-causing bacteria.

Our safe and natural antimicrobial effectively inhibits the growth of bacteria and fungi that cause odor, ensuring that your socks remain clean and funk-free.

Changing the Sweat Game

Temperature Regulation

Our traceable virgin merino wool yarns are inherently breathable and temperature regulating, allowing heat and vapor to escape from the sock while also ensuring your feet stay climate controlled - not too cold in the winter and not too hot in the summer.

Moisture Wicking

Our proprietary blend of merino wool and high performance moisture wicking yarns move sweat away from your skin and to the surface of the sock so that your feet stay dry.

Antimicrobial/Odor Control

Bacteria and germs multiply with your sweat, causing nasty odor, which is why we embedded our proprietary antimicrobial technology into the yarn. It inhibits the growth of bacteria and fungi to keep your socks clean and odor-free.

Why Purra Are The Must-Have Outdoor Socks

The Right Tool for the Job

There is a lot to like about these socks.  When I ski, I get hot and my feet tend to sweat in my boots.  It's strange being out there at 20 degrees or colder and still getting hot and sweaty but that's my reality.  I love that these socks are made from real Merino wool.  They are thin where needed but with cushioning in all the right places, especially around my toes and on my shins and, I think the breathable mesh on top of the foot helps to keep my feet at the right temperature.  If you happen to be able to extend your trip but don’t have access to a washing machine the antimicrobial feature is legit.  I squeezed 3 days in a row from 1 pair, and my socks, feet, and boots were all fresh and clean at the end of the trip.

Hiking Must-Haves

I hike every weekend with my lady & merino wool are must-haves for keeping feet dry & at the perfect temp for the weather. The no-nonsense colors are perfect for us & the cushion on the bottom of the sock makes for a more comfortable climb.

I've Been Waiting For These!

I LOVE Purra socks but as an avid hiker, I’ve been hoping they’d add Merino Wool socks to the mix. Especially for my longer hikes, I find that merino wool makes a huge difference in preventing blisters. Like all of my Purra socks, the new hiking socks are beyond comfortable - exceptionally soft & no itchy wool. I couldn’t wait to wear them on my favorite sunset hike & they did not disappoint!

Frequently Asked Questions

How can these socks improve my Outdoor Experience?

The premium merino wool yarns, embedded antimicrobial technology, and proprietary fit directly address the issues most important to serious outdoor enthusiasts. The moisture wicking yarns, temperature regulation, precise fit keep your feet comfortable, blister-free, dry and at the optimal temperature regardless of the conditions. Above and beyond, the antimicrobial keeps your feet clean and fresh so you can pack lighter and wear longer!

What does an Antimicrobial do, and why do I need it in wool socks?

  • An antimicrobial inhibits the growth of bacteria, microbes, fungi and germs that cause odor. This keeps your feet clean and fresh.
  • Although wet wool smells better than other sock fibers, it is not actually “antimicrobial” once it is sheared from a sheep, washed and prepared for yarn. By “embedding” our natural zinc antimicrobial, Purra improves the performance of merino wool.

What is Purra’s antimicrobial made from?

Zinc. Purra uses Copptech, an EPA-registered safe, natural zinc antimicrobial. Zinc is a natural element. It’s in multivitamins, lotions, shampoo, food, and even your blood. Zinc is also a major player in the creation of DNA, the growth of cells, building proteins, the healing of damaged tissue, and supporting a healthy immune system.

How do Purra merino wool socks keep my feet fresh, climate controlled and dry?

  • Breathable yarns and/or breathable mesh regulates the temperature in the socks
  • Moisture wicking yarns move sweat away from the skin and to the surface of the sock
  • “Embedded” antimicrobial technology inhibits the growth of bacteria, microbes, fungi and germs that cause odor. 
  • These features work together to keep your feet fresh, dry and at the optimal temperature.

What are the benefits of wearing Purra Performance Antimicrobial socks?

There are many benefits to wearing Purra Performance Antimicrobial socks. The antimicrobial inhibits the growth of bacteria, germs, microbes and fungi, keeping feet clean, fresh and odor-free. If needed, you can even re-wear socks without washing and still enjoy freshness. Purra socks also feature enhanced arch compression and strategic cushioning for maximum comfort, as well as breathable mesh and moisture wicking to keep your feet dry and at an optimal temperature.

How do the socks fit?

Purra socks have a proprietary and precise fit. Please use the size button and size chart on each sock to determine your exact size.
