BUILT FOR EVERYDAY PERFORMANCE
A versatile performance crew built to stay comfortable through long days, constant movement, and real-world wear.

Classic Crew Fit
Sits comfortably sub-calf for everyday wear, work shoes, and light boots

Reinforced Heel & Toe
Extra durability in high-wear zones to handle daily movement and friction

Targeted Cushioning
Strategic cushioning underfoot for comfort without overheating or bulk

Pro-Grade Alpaca Blend
Engineered for temperature control, durability, and all-day comfort
POWERED BY PRO-GRADE ALPACA™
Engineered for long days, cold ground, sweat — and the toughest conditions.


PRO-GRADE ALPACA™ FIBER
Pro-Grade Alpaca™ uses superfine alpaca selected for fiber strength and consistency, rather than baby alpaca chosen primarily for softness.
Engineered with reinforcement, it delivers durable warmth and long-day comfort under real-world wear.

BUILT FOR FRICTION
Boots create constant friction at the heel, toe, and forefoot.
Suri socks are reinforced in high-wear zones to withstand daily pressure, movement, and abrasion without thinning out.

WARMTH THAT HOLDS SHAPE
Dense terry cushioning is designed to retain loft under pressure, helping maintain warmth and support even after hours in boots.
No flattening, no cold spots, no loss of structure.

LONG DAY COMFORT
Alpaca fibers are naturally smooth and lanolin-free, helping reduce irritation during extended wear.
The result is soft, temperature-regulating comfort you can wear all day without thinking about it.

IRONCLAD GUARANTEE
Put them to the test for 365 days. If they’re not your favorite socks, we’ll repair, replace, or refund—no hassle.

MADE IN THE USA
Knit in Carolina from custom superfine alpaca yarn—small-batch quality you can feel in every pair.
Not All Alpaca Socks Are Built the Same
Most alpaca socks are built for softness. Suri is built to work.

FAQ
Why is Suri better than other alpaca socks?
Most alpaca socks are made for softness. Suri is made for long days and real wear. We use durable superfine alpaca, reinforced with nylon and a performance fit that doesn’t stretch out or slip. The result: more warmth, better moisture control, and socks that last—not just feel good out of the box.
How long does shipping take?
Orders typically ship within 1–2 business days, and delivery takes 3–7 business days within the U.S. You’ll get tracking info so you can follow your socks every step of the way.
What is the 1-Year Ironclad Guarantee?
If your Suri socks don’t hold up the way they should within a year of wear, we’ll replace them. No hoops, no fine print—just socks that work, guaranteed.
What is your return policy?
If you’re not happy with your Suri socks, you can return them for a refund or exchange. Socks must be unworn and unwashed. If something’s wrong or they don’t hold up, we’ll make it right.
Where are Suri socks made?
Suri socks are designed in the USA and made just outside of Charlotte, North Carolina, by experienced sock manufacturers.
