🧠 What to Look For in Trail Running Socks
Durability
Trail socks must withstand abrasion, rocks, and frequent washing. Look for reinforced heels, toes, and arches.
Cushioning
Medium or full cushioning helps absorb shock on rough terrain. Thin socks are for roads — not trails.
Moisture Control
Choose quick-drying fibers like merino or technical synthetics. Wet socks lead to friction and blisters.
Fit & Height
Crew or quarter-length socks protect your ankles from dirt and debris. Avoid no-shows unless on very dry trails.
