The Best Compression Socks I've Ever Worn
These are by far the best compression socks that I have ever worn. Once you have worn these socks it becomes very difficult to go back to any other brand. My legs responded to them immediately.

Hey, I'm Zach.
Co-Founder of Hollow Socks.
Compression socks were broken. So we fixed them.
But it wasn't easy.
My business partner Brian and I are outdoor guys. Skiing, cycling, hiking, you name it.
Life caught up with us. Long days. Tired legs. Swelling. Our doctors told us the same thing: "Wear compression socks."
So we tried. And we hated every second of it.
Drugstore compression squeezed like a tourniquet, left welts on our legs, and turned our feet into a swamp. The "performance" ones weren't any better.
We needed compression. We just couldn't stand wearing it.
And it pissed us off.
Making The World’s Most Comfortable Compression Socks
I had one goal: build the best compression sock in the world.
A sock with real graduated compression… that was also:
Breathable. Temperature regulating. Moisture-wicking. Odor-free.
A compression sock comfortable enough to wear all day, every single day.
The Search For Perfection
Every compression sock on the market failed at least one of those.
Drugstore compression? Squeezed like a tourniquet. Left deep red welts. Turned feet into a swamp.
Merino wool compression? Too hot. Held moisture. Took forever to dry.
Expensive synthetic "performance" compression? Same suffocating plastic. Same swamp foot. Same stink.
Nothing came close to the dream.
Nothing Worked
Then I learned what was actually happening inside those socks.
Most compression socks are made with synthetic fibers. Polyester. Nylon. Spandex.
Basically plastic.
And plastic on your skin creates problems:
It traps heat. Sweat has nowhere to go. Your feet marinate in moisture all day.
It breeds bacteria. That warm, wet environment is paradise for the microbes that cause foot odor and athlete's foot.
The enemy wasn't my feet. It was the material.
The Pivot
I had a choice: keep suffering like everyone else, or fix it.
I chose to fix it.
Brian and I went back to the drawing board. We needed a fiber that could breathe, wick moisture, regulate temperature, resist odor, AND provide real graduated compression.
Then we discovered alpaca fiber.
The hollow core of the fiber caught our attention
Tiny air pockets inside each strand. Traps warmth when it's cold. Releases heat when it's hot. Wicks moisture before it soaks in.
If nature figured this out 6,000 years ago in the Peruvian highlands.
I thought…
"Why not build compression socks with alpaca's hollow fiber technology?"
No one had done it before. So we spent two years figuring it out.
Enter: Hollow Compression Socks — the first compression sock engineered with alpaca's hollow fiber technology for all-day breathability, temperature regulation, and comfort.
A Compression Sock That Actually WORKS
All-Day Comfort:
15-20 mmHg graduated compression that supports without strangling.
Easy On/off:
Slides on in seconds. No wrestling match required.
Breathable:
Hollow fiber core allows airflow through the sock, not just around it.
Temperature Regulating:
Comfy when it's cold. Cool when it's hot. One sock, every condition.
Moisture-Wicking:
Dries 3x faster than wool. No more swamp foot.
Odor Free:
Naturally antimicrobial alpaca fiber. Wear for days without the stink.
That's how Hollow Compression Socks were born. A compression sock that doesn't suffocate your feet, doesn't leave welts on your legs, and doesn't smell like death after one day.
Plus, so soft your feet won't believe they're wearing compression.
Zero marks, Zero Pain
"Hollow compression hugs your legs like it means it, without leaving evidence of abuse."
Fiber scale height of 0.35 microns vs. wool's 0.8. That means zero itch, zero irritation, zero welts after 14-hour days. Graduated 15-20 mmHg compression that supports without strangling.
99-Day Guarantee

20-30% Better Temperature Regulation than synthetic or cotton compression
Comfy when it's cold. Cool when it's hot. One sock does both.
Hollow-core fibers trap air for insulation AND allow through-fiber ventilation. Synthetic compression just traps everything.
3-5 Days of Wear
Without Odor
Most socks fight odor with chemicals. Alpaca fiber doesn't let bacteria grow in the first place.
Alpaca fiber naturally reduces bacteria by 65-79% in one hour. No chemical treatments. Nurses wear them for back-to-back 12-hour shifts without washing.
compression without the constant sweat
"Hollow Compression Socks don't just wick sweat; they make moisture disappear before it soaks in."
Alpaca's hollow fiber absorbs just 10-11% of moisture vs wool's 30% and cotton's 27x its weight. Dries 3x faster. Goodbye swamp foot.
What Exactly is it?
Engineered with Hollow Fiber Technology
67% Baby Alpaca. 31% Nylon. 2% Spandex
Baby Alpaca = Hollow fiber core for temperature regulation + softness.
Nylon = Reinforced durability in high-wear zones.
Spandex = Graduated 15-20 mmHg compression that stays put.
Absolutely Zero:
Polyester
Cotton that holds sweat
Cheap elastic that leaves welts
Synthetic stink-traps
Why Hollow Hits Different
Other brands sell 47 sock styles.
We obsess over one thing: building the best-performing socks on earth using nature's most advanced fiber.
We obsessed over:
Fiber Selection
Baby alpaca from Peru
Graduated Compression Accuracy
15-20 mmHg
Hollow core structure
For breathability
Nylon Reinforcement
For durability
Seamless toe construction
For comfort
American Manufacturing
For quality
The Result?
A compression sock that makes you forget you're wearing compression.
Why you actually need this
You think your compression socks are fine…until you put these on. Then suddenly you're wondering:
"Why doesn't anything else feel like this?"
“Why are my other compression socks still wet from this morning?”
“Wait…my legs don't hurt and there's no marks?”
Spoiler: It’s the fiber
These socks do more for your legs than those $15 drugstore torture devices ever could.

Did You know?
Alpaca fiber was so valuable to the Inca Empire that it was reserved exclusively for royalty. They called it "The Fiber of the Gods."
For 6,000 years, alpacas evolved in the brutal Peruvian highlands — 12,000 to 16,000 feet elevation. Freezing nights. Scorching days. Ripping winds. No shelter.
Their survival depended on developing the perfect fiber.
The result? A hollow-core structure that:
Traps air for insulation when it's cold
Releases heat when it's hot
Wicks moisture before it soaks in
Resists odor naturally
Nature engineered the perfect performance fiber.
We just figured out how to put it in socks.
6,000 Years ago
Alpacas domesticated in Peru. Fiber reserved for Incan royalty.
1500’s
Spanish conquest nearly wipes out alpaca herds. Fiber knowledge almost lost.
1800’s
Alpaca fiber rediscovered by European textile industry. Becomes luxury material.
2018
Hollow Socks founded. First brand to engineer alpaca fiber specifically for performance socks.
2020
Two years of R&D.
Hollow Compression Socks launched.
Today
3 million+ pairs sold. 10,000+ five-star reviews. America's #1 alpaca sock brand.

The average person wastes $50-100 a year on compression socks that don't work. Smart people invest in compression that actually performs.
I hate compression socks. I bought four pairs from different companies. These Hollow socks are the easiest to put on, the softest, and the most stylish to wear.

FREQUENTLY ASKED QUESTIONS
How does Hollow Alpaca outperform every other material?
After two years of testing against cotton, wool, and synthetics, it became clear: nothing matches alpaca’s natural ability to keep feet dry, comfortable, and stink-free.
STAYS DRY LONGER
Unlike cotton, which traps moisture, alpaca wicks sweat away from your skin and dries fast—keeping your feet dry and blister-free all day long.
TEMPERATURE REGULATING
Thanks to its hollow-core structure, alpaca insulates in the cold and breathes in the heat, making it the rare material that’s truly comfortable in every season.
ODOR-RESISTANT & ANTIMICROBIAL
Alpaca naturally resists bacteria and odor buildup, unlike synthetics that need chemical treatments. That means fewer washes, less stink, and fresher socks for longer.
UNMATCHED SOFTNESS
Softer than wool and more comfortable than synthetics, alpaca delivers premium comfort without the itch—no matter how far you go.
How do I wash and take care of my Hollow Socks?
When caring for your Hollow Socks, we recommend washing in cold water and hanging to dry. (Note: machine washing and drying tests have shown no damage.)

Frequently Asked Questions
Will they actually feel comfortable?
Yes. Baby alpaca is softer than cashmere. These don't feel like compression socks, they feel like luxury socks that happen to provide 15-20 mmHg of graduated support. Most customers say they forget they're wearing compression.
How can compression socks be breathable?
Alpaca's hollow fiber core creates through-fiber ventilation. Air literally moves through the strand, not just around the sock. Synthetic compression traps heat because solid plastic fibers have nowhere for air to go.
Do they really not smell?
Alpaca fiber is naturally antimicrobial. The structure of the fiber resists bacterial growth without chemical treatments. Most customers wear them 2-3 days between washes with zero odor. We have reviews from nurses doing back-to-back 12-hour shifts.
Will they leave marks on my legs?
No. Our graduated compression is engineered to be firm at the ankle (20 mmHg) and lighter as it goes up the calf (15 mmHg). This prevents the "tourniquet effect" that causes welts with cheap compression socks.
Are they hard to put on?
No. These aren't medical-grade 30-40 mmHg compression that requires a wrestling match. Our 15-20 mmHg compression slides on easily. We have reviews from 93-year-olds with arthritis saying these are the first compression socks they can actually get on by themselves.
How long do they last?
12-18 months of regular wear. Alpaca has 50 N/ktex tensile strength vs merino's 30-40. Plus nylon reinforcement in the heel and toe. They hold compression after 100+ washes.
What if they don't fit?
We have a 99-Day Money-Back Guarantee. Try them for almost 3 months. If they don't fit, if you don't love them, if they don't change your life — send them back for a full refund. No questions asked.
What's Hollow's big vision?
To make the best-performing socks on earth using nature's most advanced fiber. No gimmicks. No marketing BS. Just measurably better socks for people who work hard and refuse to settle for swamp foot, leg welts, and biological warfare smell.
