I've spent years looking at what makes socks comfortable inside work boots and hiking boots, and HOLLOW's alpaca socks caught my attention. They're made in the USA, but at roughly $20 to $50 a pair, they're not an impulse buy. I wanted to find out what makes them different—and whether I'd recommend spending that much.
I've worn the HOLLOW Hunt Socks myself, and I've compared the specifications and available buyer feedback for the rest of the lineup. Below, I'll explain what I can say from firsthand experience, what other buyers report, and which models I'd consider for different uses.
Quick verdict
Buy HOLLOW if you want warm, soft, non-itchy socks that stay dry in boots, and you're happy to pay more for a made-in-USA alpaca blend.
Skip HOLLOW if you want the most durable sock for the money. Some buyers report holes within months, and several lines cost $30 or more per pair.
My pair: I've worn the HOLLOW Hunt Socks myself. You'll see photos of my actual pair below.
My picks based on features and buyer feedback: Crew Socks for everyday and boots, Compression Socks for travel and standing all day, Heavyweight Boot Socks for deep cold, Trades Socks for work boots.
What Is HOLLOW?
When I started looking into the brand, I found that HOLLOW was founded by Brian Davis, a competitive cyclist who also founded Fix It Sticks, and Zach Stuck, a growth marketer. The brand launched as "Follow Hollow" on Kickstarter in 2018 and is based in Appleton, Wisconsin. Most of its socks are knitted by a partner in North Carolina from imported Peruvian baby alpaca yarn (Garage Grown Gear brand profile). HOLLOW says it has sold more than a million pairs.
The name comes from the fiber. Alpaca hair has a hollow core that traps air, which is a big part of why alpaca socks feel warm without being thick.
HOLLOW markets these sock models to both men and women. They're sold in men's and women's sizes through Medium, Large and X-Large, so the same model works for both. Check HOLLOW's size chart on the listing to match your shoe size.
Why Alpaca? The Benefits Over Wool and Cotton
I'm used to seeing merino wool and synthetic blends in hiking and work socks. Alpaca caught my attention for several reasons:
- Warm without bulk. Alpaca fibers have a hollow core that traps air and insulates. Merino is only partly hollow (Outdoor Life).
- Less itch. Alpaca fibers have flatter scales than sheep's wool, so they feel smoother against skin.
- No lanolin. Sheep's wool contains lanolin, which a small number of people react to. Alpaca has none, so it's often called hypoallergenic.
- Dries faster. Alpaca absorbs about 10 to 11 percent of its weight in water, while merino can hold up to about 30 percent. Less water held means drier feet (Outdoor Life).
- Resists odor. Both alpaca and merino resist smell better than cotton or synthetics.
One thing I want to emphasize: HOLLOW socks aren't 100% alpaca. Most models are about 43% to 58% baby alpaca, blended with nylon for strength and spandex for stretch. The Heavyweight Boot Sock is the exception at about 70% alpaca. Pure alpaca would wear out fast in a sock, so a blend is normal, but it's worth knowing what you're paying for.
Why People Love HOLLOW Socks
When I read through Amazon's buyer feedback summaries, I kept seeing the same positives. These are buyer reports, not observations from my own testing of every model:
- Warm without being bulky. Buyers say they keep feet warm in cold weather and still fit in their usual boots.
- Very soft. "Super soft" is one of the most common comments, especially on the Trades and Ankle socks.
- Dry, comfortable feet in boots. Many buyers say their feet stay dry and the socks regulate temperature well inside boots.
- Compression that feels good. Compression sock buyers say their legs feel better at the end of the day, with less soreness.
- Made in the USA. For many buyers, that's part of the appeal.
An independent MidCurrent reviewer wore HOLLOW Boot Socks fishing on an 18°F day and said they didn't think about their feet once. They also said the socks stayed in place in tall muck boots with no bunching.
What Buyers Don't Love
I wouldn't recommend buying on the marketing claims alone. I also found some recurring complaints in buyer feedback:
- Price. Several models cost $30 to $50 a pair, and some buyers say they're not worth it.
- Durability is mixed. Some buyers say their socks hold up well. Others report holes after about five months of regular use.
- Fit can run tight. Fit gets mixed feedback. Some buyers find them too tight, especially in the calf on the compression socks.
- Breathability varies. Most say their feet stay dry, but some still get sweaty feet.
- Some shedding. MidCurrent noticed loose fibers on new pairs and after washing. It didn't affect comfort.

HOLLOW Models Reviewed
HOLLOW Alpaca Crew Socks: Best All-Rounder
47% baby alpaca, 47% nylon, 6% spandex | Crew height | 1, 2 or 4 pairs | 4.0 stars, 1,300+ ratings
If I were choosing a versatile first pair from the specifications and customer feedback, I'd start by looking at the Crew Sock. It's warm without bulk, soft and suits boots, sneakers and everyday wear. Buyers most often praise the warmth and how well they work in boots.
Buy it if you want one HOLLOW sock for daily wear, walks and light hiking.
Skip it if you need a heavy cushioned sock for deep cold. Some buyers find the crew sock thinner than they expected.

HOLLOW Alpaca Compression Socks 15-20 mmHg: Best for Travel and Standing
52% baby alpaca, 44% stretch nylon, 4% spandex | 15-20 mmHg | Knee high | 4.0 stars, 1,350+ ratings
For travel or long periods on your feet, I'd also consider HOLLOW's compression model. Graduated compression of 15 to 20 mmHg is a common level for flights, long drives and standing jobs like nursing and retail. Buyers say their legs feel better and less sore at the end of the day.
Buy it if you stand all day, travel a lot or want warm, soft compression socks.
Skip it if you have large calves. Some buyers find them tight in the calf and hard to pull on. If you have a medical condition, ask your doctor which compression level you need. For work shoes that pair well with these, see our best shoes for nurses.

HOLLOW Alpaca Ankle Socks: Best for Sneakers
46% baby alpaca, 49% nylon, 5% spandex | Ankle height | 4.2 stars, 800+ ratings
For sneakers and low hiking shoes, I'd look at the Ankle Sock rather than a tall boot sock. It's designed to bring alpaca's softness and moisture-management properties to lower-cut footwear. Buyers like the comfort and how well they keep feet dry and warm.
Buy it if you wear low shoes and want a soft, non-itchy sock.
Skip it if durability matters most. This model gets more complaints about wear than others.

HOLLOW Alpaca Trades Socks: Best for Work Boots
57% baby alpaca, 39% nylon, 4% spandex | Crew height | 4.2 stars, 230+ ratings | about $30
For work boots, the Trades Sock is the model I'd compare first. HOLLOW designed it for long workdays, with the goal of no bunching or sliding in work boots. It has more alpaca than the regular crew, and buyers call it extremely warm in cold weather and super soft.
Buy it if you wear work boots all day, especially in cold weather.
Skip it if you work in hot conditions. It's a warm sock. Pair it with a good boot from our best winter work boots or see our best boot socks for work boots.

HOLLOW Alpaca Heavyweight Boot Socks: Best for Deep Cold
70% baby alpaca, 27% nylon, 3% spandex | Heavyweight | 4.3 stars, 30+ ratings | about $30
If I needed a sock for particularly cold conditions, I'd consider HOLLOW's thickest, highest-alpaca option: the Heavyweight Boot Sock. HOLLOW claims it's three times warmer, which is the brand's own claim, not a lab result we've seen. MidCurrent's reviewer found HOLLOW's boot socks kept feet warm at 18°F.
Buy it if you stand around in serious cold, shovel snow or work outdoors in winter.
Skip it if your boots are already snug. A thick sock can make tight boots cold by cutting circulation. Read our tips to keep feet warm in work boots.

HOLLOW Alpaca Hunt Socks: Best for Hunting and Tall Boots

51% alpaca, 45% stretch nylon, 4% elastane | Over the calf | 4.1 stars, 35 ratings | about $35 | Worn by Ethan
The Hunt Sock is the HOLLOW model I can speak about from firsthand ownership. Mine is black with orange accents and reaches just below my knee, as shown in my photos. HOLLOW designed its taller fit to extend above hunting and rubber boots and to resist sliding down. I can't confirm that performance over extended use without adding my wear notes. It's also a newer model with relatively few customer ratings, so I wouldn't treat its rating as definitive.
These photos show my actual pair, not manufacturer images. The black-and-orange design and below-knee height are visible; I still want to document longer-term comfort and durability separately before making stronger claims.

Buy it if you hunt or wear tall rubber or muck boots.
Skip it if you want a short, light sock. See our best insulated hunting boots for boots to pair with it.

HOLLOW Alpaca Ski & Snow Socks: Best for Ski Boots
58% baby alpaca, 40% nylon, 2% spandex | Over the calf | 4.7 stars, 26 ratings | about $54
With ski boots, I'd prioritize a thin, close fit over extra bulk because the boots are already snug. HOLLOW's Ski & Snow Sock is designed to fit inside a ski boot, and it has the highest rating of any HOLLOW model, though from few ratings.
Buy it if you ski or snowboard and get cold toes.
Skip it if you want a sock for everyday boots. It's specialized and the most expensive model.

HOLLOW Alpaca No Show Socks: Best for Low Shoes
43% baby alpaca, 53% nylon, 4% spandex | No-show | 4.2 stars | about $20
If I wanted the lowest-profile option for sneakers or loafers, I'd consider the No Show Sock. Alpaca's dry feel helps in warm weather, when cotton no-show socks get damp.
Buy it if you want soft, low socks for summer shoes.
Skip it if you need warmth or cushioning. It's the thinnest HOLLOW sock.

How to Wear and Care for Alpaca Socks
Get the right size
I recommend checking HOLLOW's size chart rather than guessing from your usual sock size. Its listed sizes include Medium, Large and X-Large. If you're between sizes, or you find socks tight on your calves, size up.
Match the sock to your boot
A thick sock in a snug boot cuts circulation and makes feet colder, not warmer. Use the Heavyweight Boot Sock only in boots with room for it. In fitted boots, the Crew or Trades Sock is a better choice.
Wearing compression socks
Put compression socks on in the morning, before your legs swell. Roll them down, slip your foot in, then unroll them up your leg. Wear them for flights, long drives and long shifts.
Washing and drying
I'd follow HOLLOW's care instructions: wash cold and hang dry. MidCurrent's reviewer warm-washed and tumble-dried theirs without damage, but following the care label is the safest way to make them last.
Make them last longer
- Rotate several pairs instead of wearing one pair every day.
- Keep toenails trimmed. Long nails are a common cause of toe holes.
- Check boots for rough seams or worn linings that rub.
- Turn socks inside out before washing to reduce pilling.

Frequently Asked Questions
Are HOLLOW socks worth it?
If you want warm, soft, non-itchy socks for cold weather or boots, many buyers say yes. If durability per dollar matters most, the reviews are mixed. Some buyers report holes within months.
Are alpaca socks warmer than wool?
Alpaca's hollow-core fibers trap air and insulate well without bulk, and many people find alpaca warmer than merino for its weight. Warmth also depends on sock thickness and boot fit.
Do alpaca socks itch?
Alpaca usually itches less than sheep's wool because its fibers have flatter scales. It also has no lanolin, which some people react to.
Are HOLLOW socks really made in the USA?
Yes. HOLLOW says its socks are knitted in the USA, mostly in North Carolina, from imported Peruvian baby alpaca.
Can you put HOLLOW socks in the dryer?
HOLLOW's listings say to hang dry. Some reviewers have tumble-dried them without problems, but hang drying is safest.
Do HOLLOW socks run small?
Fit gets mixed feedback, and some buyers find them tight. Use the size chart and size up if you're between sizes.
Are HOLLOW socks unisex?
HOLLOW markets its socks to men and women. Check the model-specific size chart rather than assuming every model fits identically.
Are alpaca socks good for sweaty feet?
Alpaca absorbs less water than merino and dries faster, which helps. Most buyers say their feet stay dry in HOLLOW socks, but some still sweat, so results vary.
The Bottom Line
My takeaway is that HOLLOW is worth considering if you value alpaca blends, warmth without excessive bulk, and USA manufacturing. I own the Hunt Socks, but I won't pretend I've personally stress-tested the entire range. The biggest reasons I'd hesitate are the price, mixed reports about durability, and fit complaints from some buyers. Here's where I'd start depending on your needs:
- Everyday and boots: HOLLOW Crew Socks
- Travel and standing all day: HOLLOW Compression Socks
- Work boots: HOLLOW Trades Socks
- Deep cold: HOLLOW Heavyweight Boot Socks
- On a budget: Alpacaparty Alpaca Crew Socks
