THORLO'S Military Boot Moderate Mid-Calf Performance Sock M (EU 38-42) – 85% Thorlon® Acrylic, Unisex, Moisture-Wicking

High-density padding in impact zones delivers shock absorption that keeps you moving through long hours in combat, work, or hiking boots. The Thorlo Military Boot Moderate Mid-Calf Sock is built with 85% Thorlon® acrylic fibers that wick moisture away from the skin, reducing friction and preventing blisters even in demanding conditions.

Overview

Thorlo’s military-grade construction combines targeted cushioning with a supportive fit. The moderate mid-calf profile sits comfortably under boot shafts, while the flat-knit toe seam minimizes blister risk. Ventilation zones improve airflow, and the built-in arch support keeps your foot stable on uneven terrain. The sock's contour fit hugs the foot and calf, reducing slippage and hot spots. Reinforced heel and toe areas enhance durability in high-wear zones, while the moderate cushioning balances protection with agility inside tight-fitting boots.
