“Was skeptical about the back pocket, but my phone stayed completely put during a hilly 6-miler. The support is fantastic too, no bounce and more importantly, no chafing under my pack. I'm buying another one.”

Born in the mountains. Built for real runners.
ALPYN was born in the mind of a mountain kid. Long days on ridgelines, changing weather, and the simple rule that comfort and focus decide your day. From that mindset came a clear idea: make fewer things, make them right, and keep runners close to nature with gear that actually helps.
Less stuff. Better runs.
ALPYN designs essentials that solve real problems: dry feet, no hotspots, stable carry, faster recovery. Trail-tested across Colorado and Utah, each piece is tuned for feel, durability, and miles.
- No-blister comfort and fast-wicking performance
- Locked-in support for cleaner form and longer efforts
- Merino and performance knits that breathe and last
Premium where it matters, minimal where it doesn’t.
ALPYN keeps quality high and impact low: thoughtful materials, durable construction, small production runs. Lean packaging, reduced waste, and fair, transparent pricing. So you don’t pay for hype, you pay for gear that works.
Run farther. Feel better.
Put ALPYN on your next outing. If it doesn’t make your miles better, it doesn’t belong on the trail. Our 99-Day Run-Test Guarantee applies on select items.

“I run in the Texas heat and this is the first high-impact bra I've owned that doesn't feel like a swampy straightjacket after 30 minutes. It's supportive, yes, but the mesh panels are a game-changer for staying cool.”
Brooke H.
“Wore this for a 4-hour trail run and forgot it was there. The band didn't ride up, the straps didn't dig in. Just solid, comfortable support. Well worth the price.”
Hailey V.
“Perfect balance of cushion and breathability. My feet stayed dry and blister-free through a muddy 20-miler. Plus, they didn't stink at all afterwards. Merino wool is magic.”
Caleb R.
“I'm tough on my gear, and these have held up to rocky trails and countless washes. They've got this soft, cushioned feel but my feet never overheat. Ditching my old synthetic socks for good.”
Grayson T.
“I was so worried about my feet for my first 50K. A friend recommended these and they were lifesavers. Not a single hotspot, even with two creek crossings. Incredible.”
Sierra K.
“I wanted a lighter sock for summer and these are it. Super breathable, light, and the little heel tab is brilliant—no slipping down into my shoe. My feet stay way cooler.”
Quinn D.
“Great sock for when you want protection without the height of a crew sock. The fit is snug, the cushioning is just right, and they feel fast. No issues with rubbing on my Achilles.”
Preston A.
“I use the crew version for ultras, but these ankle socks are my favorite for anything under 15 miles. They just disappear on your feet. Same great merino comfort, less sock.”
Kendall B.
“Wore these for a race with a ton of vertical gain and my calves felt noticeably fresher on the final climbs. The compression is supportive without being suffocating. Great race sock.”
Jaxon L.
“I have incredibly sweaty feet and most socks are soaked after an hour. The Coolmax fabric is insane, it just pulls the moisture away. My feet stayed dry through a whole humid afternoon run.”
Cassidy F.
“The perfect blend of support and cooling. I was looking for a compression sock that wasn't crazy hot. This is it. Performed flawlessly during a hot marathon.”
Wyatt S.
“Literally saved my runner’s knee. I was getting sharp knee pain on every downhill. This sleeve supports exactly where I need it. Back to pain-free trails.”
Skylar J.
“My legs feel more stable and less fatigued on long runs. The top band actually stays put and doesn’t roll down.”
Holden P.
“Post-workout recovery is way better when I wear this for a few hours. Next day soreness is noticeably lower.”
Avery G.
“This is the first vest I’ve owned that truly doesn't move. Fully loaded and still zero bounce or chafe. Blown away.”
Lincoln W.
“Pocket layout is brilliant. Phone secure, flasks easy to grab, gels up front—fuelling without breaking stride.”
Morgan T.
“As a bigger guy, the adjustable straps are a lifesaver. Fits perfectly without feeling restrictive.”
Easton H.
“Came with everything out of the box and performed perfectly on race day. Great value.”
Peyton R.
“So lightweight and breathable I forgot I had it on. Carried all I needed without feeling weighed down.”
Flynn C.
