Size Chart
Sock Sizing
Socks should fit as well as any of your other garments. The heel should sit on your heel and not under it as in a sock too small, nor half way up your Achilles as in a sock that’s too large. Socks should be flush against your foot with no extra material sagging. The toe seam should lay flat across the top of the toes.
Sock Heel at Your Heel
The sock heel should sit on your heel, not under it or above it.
Flat Toe Seam
The toe seam should lie flat along the top of your toes, not above or below.
Taut Across the Foot
Socks should be taut across your foot with no sagging material. If you wear a wide shoe size (E+), consider sizing up.

| Large | 9.5 – 11.5 | 10.5 – 12.5 |

Insole Sizing
The right insole can make a significant difference to your comfort. The insole should fit the shape and contour of your shoe and the length should be a perfect match. The toe of the insole should not crumple up against the inside of the shoe, nor should it be too short.
Insole Matches Shoe Contour
The insole should fit the shape of your shoe, without any overhang or gaps.
Perfect Length
The insole should match the length of your shoe perfectly. The toe of the insole should not crumple or be too short.

PRODUCT OF CANADA
Our Bison Fibre BOOT LINERS are simply the warmest that you can buy. Made with 100% Canadian Bison Fibre blended with Canadian Wool (50/50) and produced completely in Canada.
These Boot Liners will keep your feet warm in the coldest of weather. Our boot liners wicks moisture like only bison fibre can, and stays springy and resilient much longer than any poly-based foam. Keeps you comfortable and your feet dry all year long.
Natural fibres wick away moisture, absorb foot odour and keep your feet dry while adding additional comfort to your step. You can hand wash them in warm water with a wool-friendly soap and air dry to keep them clean and odourless, but we recommend you only occasionally do that, as they are very anti-ordour.
Don't underestimate the value of a good quality natural fibre liner, they can add another 15 to 20 degrees of cold protection to your boots, and quality insoles may allow you to wear a lighter boot in colder weather. This is particularly nice for hunters, who may start the day sitting on a stand and then end up doing a lot of walking. Or if you work on cold concrete all day, you may be able to wear those comfortable work boots year round. Without a doubt -this is the warmest boot liner on the market!
Material Composition
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.
