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.
