1. What makes ALPYN Merino socks better than cotton or synthetic socks?

It comes down to superior performance in the conditions where it matters most. After extensive testing, we engineered our signature merino wool blend to solve the biggest problems trail runners face:

ALL-DAY DRY COMFORT
Unlike cotton which absorbs sweat and causes blisters, our premium merino wool blend wicks moisture away from your skin to keep your feet dry and comfortable, mile after mile.

PERFECT TEMPERATURE REGULATION
Merino’s natural fibers insulate when it's cold and breathe when it's hot. The result is a sock that performs just as well on a frosty morning run as it does on a hot afternoon climb.

NATURALLY ODOR-RESISTANT
Merino wool naturally fights odor-causing bacteria, unlike synthetics that can get smelly quickly. That means you can wear them for multi-day adventures and they’ll stay fresher for longer.

PREMIUM SOFTNESS, NO ITCH
We use ultra-fine Australian merino wool that feels incredibly soft against the skin, offering premium comfort without the itch associated with traditional wool.

2. Are these socks really blister-proof?

While no sock can be 100% "blister-proof" for every person in every condition, ours are engineered to eliminate the primary causes of blisters. The combination of a

seamless toe, a locked-in arch support that prevents slipping, and advanced moisture-wicking from our merino blend drastically reduces the friction and moisture that lead to hotspots and blisters. Our "Run Blister-Free" promise is one we stand by.

3. What size should I get?

Finding the perfect fit is key for performance. Please refer to our sizing chart below, which is based on US shoe sizes. If you are between sizes, we generally recommend sizing down for a snugger, more compressive fit.

• Medium: Men 8-10 / Women 7-10
• Large: Men 10.5-13 / Women 10.5-12
• Extra Large: Men 13.5-15

You can also find the size chart in the image gallery above.

4. How do I wash my ALPYN socks?

To ensure a long life for your socks, we recommend washing in cold water with like colors and tumbling dry on low. Please do not use bleach or fabric softeners, as they can degrade the performance of the merino wool fibers.
