Mountain Heritage Microweight Liner Merino Wool Ankle Socks
When you want sock protection without sock bulk, these ultra-thin merino wool ankle socks deliver a barely-there feel with real performance features. The liner-weight construction sits just above the ankle, giving you coverage where shoe collars meet skin without adding thickness to your footbed.
At 58% Australian merino wool, these thin ankle socks outperform synthetic liners on every metric that matters: moisture wicking, odor resistance, and temperature regulation. Where polyester traps heat and breeds bacteria, merino actively moves sweat away from your skin and neutralizes odor-causing microbes naturally.
Liner Construction, Real Protection: The microweight design means no cushioning or terry loops—just smooth, thin fabric that disappears inside your shoe. But thin doesn't mean fragile. Heel and toe plating adds durability where socks wear fastest, while a lightly padded toe bumper protects against front-of-shoe impact. The Y-heel creates a perfect pocket that stays put without bunching.
Built to Breathe: Vented zones across the top of the foot let air circulate freely, keeping feet cool during warm-weather activities. Three-zone elastic at the arch, ankle, and welt opening ensures these socks stay in place whether you're trail running, cycling, or putting in everyday miles.
Why Liner Socks Matter: For hot-weather activities, a thin wool sock keeps feet drier and cooler than going sockless or wearing thick cushioned socks. For cold-weather layering, these work beautifully under heavier socks to add warmth and reduce friction. Either way, merino wool's natural properties work harder than synthetic alternatives.
Specifications: 58% Merino Wool, 22% Nylon, 19% Stretch Nylon, 1% Spandex. Weight: 34g per pair. UPF 20 sun protection. Machine wash cold, tumble dry low. Made in New Hampshire, USA.
