Hike Full Cushion Crew Socks

Our Hike Full Cushion Crew socks, formerly PhD® Outdoor, use cushioning on the entire sock to help maximize warmth and protection. These responsibly sourced, ZQ-certified Merino wool hike socks are built with our top sock tech, including Indestructawool™ technology for enhanced durability, our 4 Degree™ Elite Fit System for a dialed-in, performance-oriented fit, and our Virtually Seamless™ toe for maximum in-shoe/boot comfort. We've updated our hike line by improving mesh zones for additional breathability, as well as creating a new ply structure that reduces pilling while enhancing hand-feel and comfort. Not to mention, our best-feeling, best-fitting hiking socks are now made with recycled nylon—making these socks more sustainable than ever. Now that's something you can feel good in and about.

Indestructawool™ Durability Zones
Indestructawool™ technology with extended durability zones is intentionally knit into high-impact wear zones — the heel, toe, and ball of the foot. The reinforcement is in the knit itself, so it doesn't wash out or pill down over hundreds of trail miles.
4 Degree™ Elite Fit System
Performance fit with strategic stretch and mesh zones promotes breathability while helping protect against blisters. The four-point compression band keeps the sock locked to the foot through heel-strike, midstance, and toe-off — no bunching in the boot, no sliding into the toe box.
Virtually Seamless™ Toe
Flat-knit toe seam sits flush against the foot — no ridge, no rub, no hot spot. Designed for additional comfort on long miles where toe irritation ends hikes early.
Full Cushion, Full Foot
Cushioning on the entire sock — not just under the foot — for maximum warmth and protection. Medium thickness with full sock cushioning balances impact absorption with pack weight, the right amount of padding for cool-to-cold weather hiking.
Updated Mesh Zones
Improved breathability through the upper foot. The mesh zones let heat and moisture escape so feet stay cooler on warm-weather hikes and high-output days. New ply structure reduces pilling while keeping the knit soft against the skin.
Comfort Welt With 'Stay Put' Fit
A knit-in welt around the cuff keeps the sock from sliding down into the boot. The welt is knit into the sock rather than sewn on as a separate band, so it doesn't dig in or wear out at the edge.
Crew Height Coverage
Crew sock height rises above the ankle for extra coverage on the trails — keeps debris out of hiking boots and adds a small layer of warmth around the lower calf.
Made in USA of Imported Yarn
62% Merino Wool, 36% Nylon, 2% Elastane. Knit in the USA from imported yarn. The recycled nylon backbone adds structural durability; the elastane adds stretch recovery; the Merino does the work against the skin.

Washing
Machine wash on a gentle cycle in warm or cool water. Turn socks inside out before washing to protect the outer knit and help release body soil from the cushion. Avoid fabric softener, which coats Merino fibers and reduces moisture-wicking performance.
Drying
Tumble dry low. Heat helps the Merino fibers re-loft and restores cushion volume. High heat can shrink the sock and damage the elastane recovery — keep the setting low and remove promptly.
Bleach & Iron
Do not bleach. Do not iron. Bleach breaks down Merino wool fibers and destroys the elastane; iron heat can scorch the knit and flatten the cushion loft.
Dry Cleaning
Do not dry clean. The harsh solvents used in commercial dry cleaning strip the natural lanolin from Merino wool and degrade the nylon/elastane construction — both of which are core to the sock's performance.
Storage
Store paired and unfolded in a dry space. Merino's natural odor resistance means you can wear socks multiple days between washes on multi-day trips — the perfect performance feature for backpacking and travel.

Merino Layer System — SW001618

Built For

Day Hiking
3 Season
Single-day trails in hiking boots where a light sock doesn't have enough cushion but a heavy sock is overkill. Full Cushion hits the middle — enough padding for the descent, breathable enough for the climb, with the 4 Degree™ Elite Fit System keeping the sock locked through the gait cycle.
Backpacking
Multi-Day
Multi-day trips where Indestructawool™ zones survive hundreds of trail miles and the full-foot cushion protects against the heel bruise that comes with a heavy pack. Merino's odor resistance means wearing them multiple days between washes on a section hike.
Cool-Weather Hiking
Cool — Cold
Fall and shoulder-season days when the temperature drops below 50°F and the wind cuts through a lighter sock. Full Cushion adds insulation without the bulk of a heavy sock, and the updated mesh zones dump excess heat before the foot overheats.
Hut-To-Hut Treks
Multi-Day
Long-distance walking days in stiff leather boots where the comfort welt prevents the cuff from digging in, the Virtually Seamless™ toe prevents blisters on the downhills, and the recycled nylon backbone survives the daily wash-and-dry cycle of a multi-day trek.
Build The Stack

Pair It With A Boot

The Hike Full Cushion is built for hiking boots with real structure — leather or synthetic mid-height boots that hold up under load. Full Cushion is wasted in a trail runner; it shines when the boot doesn't give.

  • Mid-height hiking boot day hikes + structure
  • Backpacking boot multi-day with a pack
  • Leather hiking boot break-in comfort + durability
  • Approach shoe scrambling + light loads
Complete The Kit

Layer Up Top

The Hike Full Cushion is the foot half of a complete layering system. Pair it with a Classic Thermal Merino Base Layer Crew or Bottom for head-to-toe Merino performance on cold hikes.

  • Merino base layer crew moisture management
  • Merino base layer bottom matched warmth
  • Smartloft vest core insulation
  • Hardshell jacket full weather protection

Prepared with intention.

Every product is carefully inspected and handled by our team before it ships. From fit and function to final details, we make sure each piece is ready for the outdoors ahead—so you can focus on the experience, not the gear.
