  • Warmth that works even wet — A 48% alpaca blend, our highest-content sock, runs about three times warmer than sheep's wool and keeps generating heat even if it gets damp.
  • Terry-lined foot, over-the-calf coverage — A fully cushioned footbed and a wide-ribbed leg that runs over the calf protect against boot-edge chafing and cold from toe to knee.
  • Expands to fit, never binds — An extra-wide comfort cuff stretches to fit any calf size without cutting in, so circulation and comfort aren't a trade-off.
  • Hypoallergenic, wool-free comfort — 100% free of sheep's wool and lanolin, with reinforced heel and toe that hold up through boots, hikes, and everything between.

How we rate

Temperatures are a guide for everyday wear. Active days run warmer.

Your legs deserve better than the cold that creeps up from your ankles. The Second to None Alpaca Boot Socks are built for exactly that problem: a 48% alpaca blend, our highest-content sock, that runs about three times warmer than sheep's wool and keeps you warm even if it gets wet. A terry-lined foot cushions every step, while a wide-ribbed leg extends over the calf to shield you from boot-edge chafing. The extra-wide comfort cuff expands to fit any calf without binding, so you get real warmth without ever feeling restricted. Wool-free and hypoallergenic, these hold up through work boots, hiking boots, or a slow night by the fire — reinforced heel and toe included.

Fabric Content

Why alpaca

Alpaca vs. Merino Wool vs. Cotton

How alpaca fiber stacks up against the two most common sock materials, rated honestly.

This sock: Extreme Cold warmth, Extra Soft softness

Comparison of alpaca, merino wool and cotton sock fibers
Feature Warrior Alpaca Merino Wool Cotton
Warmth Best Hollow fibers trap heat, warmer than wool without the bulk Good Warm, but needs more bulk for the same heat Poor Little insulation, and none once it gets wet
Moisture-wicking Best Pulls sweat away and dries fast Good Wicks well, dries more slowly Poor Absorbs sweat and stays wet
Odor resistance Best Naturally antimicrobial, stays fresh in boots Good Resists odor well Poor Traps odor after a day of wear
Itch-free softness Best Smooth fiber scales, no prickle Good Soft, though some feel a prickle Good Soft and itch-free
Sensitive skin Best Lanolin-free and hypoallergenic Fair Contains lanolin, which can irritate Good Gentle on most skin
Durability Best Strong fiber that holds its shape Good Durable, prone to felting if overheated Fair Wears thin and stretches out

Reviews

Season ready

"Ready for a cold deer hunting day in December, so I have not had a chance to try them out. Look land feel like the socks will do a great job. Great service from Warrior."

— HENRY S. (5/5)

— KARL S. (5/5)

soft and warm

— jack p. (5/5)

I love them!

"These are the best socks for my cold feet and shins, I love them!"

A big hit!!

"Bought these for my husband and he loves them! They are so soft and warm. A real hit!!"

— JEANIE L. (5/5)

Soft, fluffy and warm

"We love the socks. Small size went over my knees (I’m 5’2”) which is a bonus. They feel soft, fluffy and warm but the real test is when we wear them in Fairbanks in March in sub-zero temperature under snow boots."

— LISA L. (5/5)

Nice socks!

"Looking forward to seeing how they perform when I hunt."

— JOHN L. (5/5)

over the calf socks

— MARJORIE D. (5/5)

Warm and soft

"I love these socks, they are so soft and keeps my feet and legs warm."

— PAMELA F. (5/5)

Soft, cozy, and so warm!!

"This is the second pair of alpaca socks I’ve bought. These boot socks fit perfectly and go over my knee. I wore them ice fishing and my feet stayed warm. The color is beautiful, and they are so soft and cozy. My only issue is the fact that they started pilling the first time I wore them. It’s not a huge deal, but the pilling started before I’d even washed them. I’m going to wash them on delicate and be careful with them and hopefully it won’t get too bad. If it weren’t for that, I’d have given them five stars for sure!"

— DONNA F. (4/5)

Q&A

Do you need a liner sock with these?
With our Second to None Thick Alpaca Socks – Boot / Over‑the‑Calf, you do not need to wear a separate liner sock underneath. These socks are designed as a premium, all-in-one solution: they feature a terry-lined foot for extra cushioning, a thick alpaca wool blend for insulation, and a durable construction that works well on its own. If you’d like a lighter feeling or need something moisture-wicking for high-intensity activity, you could pair a thin liner sock underneath, but it’s absolutely optional — the product was created to perform without one.
