Frequently Asked Questions
Frequently Asked Questions
1. What makes ALPYN Merino socks better than cotton or synthetic socks?
Our signature merino wool blend offers superior performance where it counts. It wicks moisture to keep feet dry and blister-free, regulates temperature to stay cool in the heat, and is naturally odor-resistant. It’s softer than synthetics and far more durable and quick-drying than cotton.
2. Will these ankle socks slip down into my shoes?
No. We specifically designed them with a snug, locked-in arch support and a protective anti-rub heel tab. This combination ensures the sock stays perfectly in place during your entire run, protecting your Achilles from chafing and preventing any slipping or bunching.
3. What size should I get?
Finding the perfect fit is key. Please refer to our sizing chart below. If you are between sizes, we 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
4. How do I wash my ALPYN socks?
To ensure a long life, 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.
5. What is the 99-Day Trail Test guarantee?
We're so confident you'll love your socks that we offer a 99-day risk-free trial. Run in them, hike in them, and put them through their paces. If for any reason you're not satisfied with the fit or performance, you can return them for a full refund or exchange - no questions asked.

My go-to sock for summer
I run in Texas and my feet used to overheat constantly. These ankle socks are a game-changer. They're so breathable and light, and my feet stay dry even on the most humid days. No blisters, just comfort. Finally.

Perfect for race day
I wanted a minimal, lightweight sock for my last trail half-marathon and these were perfect. The heel tab is brilliant—the sock didn't slip at all, even on steep descents. Felt fast and my feet were flawless at the finish line.

The first ankle sock that actually stays up
I’ve always avoided ankle socks for trail running because they slip down and give me blisters. Not these. The fit is snug and the heel tab really locks it in place. Wore them for a 3-hour run and never had to adjust them once. I’m converted.

All the merino benefits, less bulk
I love merino crew socks for winter, but wanted something lighter for the rest of the year. These are it. You get that same amazing softness and odor resistance, but in a light, breathable package. My feet are happy.
