Over the calf, and over the top.

This is a four season sock, great cushioning and support for standing in a river tossing flies at salmon, long hikes, hard hunts, and basically just keeping your feet dry and comfortable in most conditions.  They will stay fresh and funk free for days on end... pack less, travel more.  Less bulk and better fit, not quite as insulating as our Trekker or Pro-gear socks, but built to take whatever you can throw at them and still keep you cozy. 

The Buffalo Wool Co. Kenai Boot Socks feature:

  • URfit System for arch support and memory-knit construction
  • Smooth and flat comfort toe seam
  • Footbed is a luxurious bison down, ultra-fine merino, bamboo blend
  • Leg Shaft is an extremely comfortable military-spec polypropylene
  • Bison on toe indicates size (photo shows a large); small - brown, medium-yellow, large-blue, xlarge-red

Knit for us at Fox River Mills in Osage Iowa, those sock-creating geniuses marry military spec polypropylene on the sock shaft with our close-to-bulletproof bison down/ultra fine superwash Merino wool, and bamboo yarn blend in the foot. (the same yarn we use in our B.O.S.S. socks.) 

Anyone that has ever worn a pair of military polypro socks knows how supportive they are, but you have never felt the footbed comfort and warmth of our bison/merino/bamboo yarn blend at the same time.

The result is the exact sock that Fox River knits for the US Military but with your feet surrounded with the warm, moisture-wicking, comfortable, durable proportions of our BOSS Sock. This Mil-Top sock is about 3" taller than our Trekker boot sock ... right at mid-calf ... and with the stay-in-place power of mil-spec polypropylene.

As to scent capturing,  We had one of our spec testers, who claims to have worn them a ridiculous 12 days of elk hunting.  Now that would just be "Socks Abuse"!  But these are the top of the hunting/moving/walking sock food chain.  They are my "go-to" hard-wearing outdoor socks anymore.

      Sock Sizing

      Socks should fit as comfortably as any other garment. The heel should rest on your heel—not under it (as with a sock that’s too small) or halfway up your Achilles (as with a sock that’s too large). The sock should be snug against your foot with no sagging fabric. The toe seam should lie flat across the top of your toes.

      Sock Heel at Your Heel
      The heel of the sock should sit directly on your heel, not above or below it.

      Flat Toe Seam
      The toe seam should lay flat along the top of your toes, not above or below them.

      Taut Across the Foot
      Socks should fit snugly across your foot without any sagging material. If you wear wide shoes (E+), consider sizing up. If you wear a wide shoe size (E+), consider sizing up.

      Care Instructions

      Machine wash and dry

      Once you are ready to clean your gear, follow a few simple steps to care for your favorite socks, beanie, and gloves.

      How to Care for your favorite bison fiber gear

      Material Composition

      Here at The Buffalo Wool Co., our yarn bases for all our gear is (and will always be) natural fibers. This means that the internal structure of your socks (the parts that touch your skin) will be made from bison fiber, merino wool, mulberry silk, and other 100% natural fibers.

      The overall composition (the parts that touch your skin plus everything else) will include other materials like nylon or polyester. This is done to make the sock more durable and ensure that your socks work (and play) as hard as you do.

      Love

      I have several pairs of these socks and wear them all the time! I love them! They are comfortable and keep my feet warm.

      Cozy warm

      The socks have lots of cushion so they're great when you're on your feet all day. I've worn them in subzero temperatures for long periods and my stay today warm. Even after I've been inside half the day and stay out in subzero weather. No wet cold feet.

      Just okay

      I purchased these with hopes of not having cold feet when doing chores. I really wanted them to work as we also raise bison and that made the cool factor over the moon. However, the socks struggled to stay up and my feet were still getting cold. The do look super cool though.

      Great Socks

      Awesome warm socks

      Would have been a 10 but they run a little small ! Feet never get cold while wearing!!

      They were light, comfortable, warm, and keep my feet dry.

      The best socks

      These socks are perfect- the height and the thickness is just right for me. I’ve tried other quality wool sock brands but the toe area is always too tight for me. These have space for my toes to spread! Will be coming back for sure!
