"I swear to God, these Hollow socks are all I wear now. They're made from alpaca wool and are super temperature-regulating. You can takethese boot socks and wear them from literally subfreezing and your toes don't get cold to 80° and you don't notice the difference."
-
"I'm ditching all my crappy socks because Hollow alpaca socks are just so much better. They keep my feet nice and toasty in winter, yet dry and cool in summer. It's like hugging your feet with the most comfortable fabric you could ever imagine. These are going to be on my feet at all times!"
-
"Hollow Socks are the best socks I've ever worn ever. They keep my feet dry by wicking moisture away so my feet aren't sweaty all day. The hypoallergenic properties mean my feet never stink ever! I used to get that 'zombie foot' feeling after a long day in boots, but with Hollow Socks, that's a thing of the past."
-
"One thing I love about these Hollow socks is that you get to wear the same sock whether it's hot or cold. A week ago I was skiing in freezing temperatures with warm feet, and now I'm in a hot gym with cool feet. My feet stay dry in any condition, allowing me to perform my best."
QUESTIONS? WE HAVE ANSWERS.
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.
