Heavy Weight Crew Hiking Socks
Maximum protection. Every step.
Some trails don't go easy on you. Jagged rock. Steep descents. Cold mornings that bite through your boots. Days that start before sunrise and don't end until after dark.
Our hiking crew heavyweight socks is our most protective hiking sock - cushion throughout the entire sock, from toe to cuff. Full warmth, full impact absorption. These are heavyweight merino wool hiking socks for cold weather, rough terrain, and long days when lighter socks would leave you hurting.
The toughest days deserve the toughest sock.
About This Sock
We call this our heavyweight for a reason. It packs more merino wool than any other sock we make. Full cushion from toe to cuff. No thin spots, no shortcuts.
On a cold morning at elevation, your toes stay warm. On a 15-mile day with a loaded pack, your feet don't get tender. On a rocky descent, the padding underfoot absorbs the impact while the crew height protects your shins inside tall boots. This is the sock for winter hiking, shoulder-season backpacking, and any trip where cold or sore feet aren't acceptable.
The 100% merino wool body yarn does what merino is known for: temperature regulation, moisture wicking, and odor resistance that holds up over days of wear. Nylon reinforcement at the heel and toe keeps the sock from wearing through where it takes the most abuse. Seamless toe closure means no rubbing, no blisters.
If you hike in the cold, this is the pair. If you are heading up a mountain where the weather can flip in an hour, this is the pair. If you just run cold and want the warmest merino wool hiking sock we offer - this is the pair.
