Men's Merino Wool Compression Sock - Slate Blue - Ultralight

Featherweight feel, full-time support. Our Slate Blue ultralight compression sock is built for runners, hikers, and travelers who want every advantage and zero extra weight.

Moderate graduated compression wraps your calves in smooth, stay-put pressure that helps keep swelling down and your legs feeling strong deep into the day. And with no bulky cushion, these slide into your lightest trail runners and closest-fitting boots with room to spare.

Cloudline's signature merino wool pulls moisture off your skin, keeps odor in check, and dries fast, so your feet stay cool and comfortable even when the pace picks up.

Race day, travel day, or just a Tuesday that won't quit: go lighter, go longer. Your legs will notice.

Frequently Asked Questions

What size should I get?

Men's sizes follow your US shoe size: Small Youth 3 - 5.5, Medium fits 6 to 8.5, Large fits 9 to 11.5, and X-Large fits 12 to 14.5. If you're between sizes, size down, since the merino and spandex blend stretches for a snug fit. If you have wide or high-volume feet, size up. See the full size guide.

How much compression do these have?

They have 15 mmHg of moderate, graduated compression. They're snuggest at the ankle and ease up toward the calf, so they feel supportive without being restrictive. Ultralight is our thinnest, coolest compression sock. For a little padding underfoot, try our Light Cushion compression sock.

Can I wear them on a flight?

Yes. They're a favorite for travel. Moderate graduated compression helps legs feel less tired and swollen on long flights, drives and shifts on your feet, and the merino stays comfortable and fresh for hours. If you have a medical condition or a doctor has recommended a specific compression level, check with them first.

Should I wear them during activity or after?

Both work. Wear them on long hikes, runs and days on your feet for support, or put them on afterward to help tired legs recover.

How should I wash them?

Turn them inside out, machine wash cold or warm with like colors, and tumble dry on low to warm heat. Skip bleach and fabric softener, because softener can reduce wicking. Every sock is preshrunk, but high heat can still shrink wool over time. Full tips are in our washing guide.

What does the lifetime guarantee cover?

If your socks ever get a hole, or your dog eats your favorite pair, send us the guarantee form with your order number, or the name and email you ordered with. Our in-house team will replace them.
