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

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.

      You won’t be disappointed!

      The whole process from order to delivery was great.
      The socks are amazing!
      I’ve never had socks that were this warm and comfortable!

      My new forever sock

      Bought the Kenai socks just before gun season. I wore 2 pair for 10 days. Walked miles through U.P. swamps. No stink, or sweaty feet paired with my rubber boots. They will replace my Darn tough, and Farm to feet. Treat your feet. Buy them.

      Great Socks

      Bought them for an elk hunt in Wyoming this year. Kept my feet warm and comfortable for all 7 days. My feet sweat easily and these kept the moisture off my feet. Highly recommend.

      Perfect Socks!

      Have been wearing these daily as part of WNC recovery efforts and fire/SAR calls. The fit is great, and I’ve been kept warm and dry - and cool - in all sorts of elements. Glad I found these, and am also thankful for Ron’s support of our recovery efforts!

      Awesome Socks!

      I ordered these socks to wear while training dogs in the cold weather. They are perfect! Very comfortable and warm. If you are looking for a good pair of socks for every day work these are what you need to order!

      Best boot socks!

      Although I'll wear the heavyweight socks in the coldest weather, these immediately became my favorite boot socks, and I look forward to buying at least 1 more pair. They're comfortable, warm (without becoming hot in warm weather), moisture wicking, and they stay up over the boot collar pretty well, but don't sag, which helps to eliminate bunching, heel rub, etc. They have padding in just the right places.
