Description & Features
The Accapi FIR Ski Racing Sock is Accapi's ultra-thin race sock, measuring just 0.3 mm for maximum sensitivity and a precise fit inside close-fitting ski race boots. TFT Touch Feel Technology and MIKRO ultra-thin fiber construction minimize material between the foot and boot, helping racers maintain direct feedback and precise control without sacrificing warmth or comfort.
Accapi's infrared fiber absorbs natural body heat and reflects it back as Far Infrared (FIR) energy to support circulation, thermoregulation, and muscle oxygenation. This allows the Accapi FIR Ski Racing Sock to maintain an exceptionally thin profile while helping keep feet warm, reduce in-boot swelling, and delay foot fatigue. EQT Equilibrium Technology further supports balance, proprioception, and postural awareness for performance-focused skiing.

Construction & Technology
Accapi Far Infrared (FIR) Fiber
Accapi's infrared fiber absorbs the body's natural heat and reflects it back as Far Infrared (FIR) energy in the 5–20 micron range. According to Accapi, this continuous infrared interaction supports circulation, muscle oxygenation, and thermoregulation, helping keep feet warmer while reducing in-boot swelling and delaying fatigue. Because warmth and thermal regulation are provided without relying on bulky insulation, Accapi can engineer the Ski Racing Sock to an exceptionally thin 0.3 mm profile for precise race-boot fit and sensitivity.
TFT Touch Feel Technology
TFT Touch Feel Technology minimizes the amount of material between the foot and ski boot to increase tactile feedback. Combined with the 0.3 mm profile, it gives racers a direct connection to the boot for precise pressure control, sensitivity, and response.
MIKRO Ultra Thin Fiber Technology
MIKRO ultra-fine fiber construction helps the sock achieve its exceptionally thin profile while maintaining functional coverage inside the ski boot. The low-bulk construction is particularly well suited to close-fitting race boots where excess sock material can compromise fit and sensitivity.
EQT Equilibrium Technology
EQT Equilibrium Technology is tuned to the body's natural equilibrium to support stability, balance, proprioception, and agility. For alpine racers, this increased body awareness complements the sock's direct boot feel by supporting precise movement and postural response through gates and technical terrain.
Race-Precise Anatomical Construction
Anatomical left and right shaping creates a more precise fit around each foot, while reinforced heel, toe, and shin zones add durability and protection in critical areas. An accordion elastic forefoot band helps secure the sock against the foot to minimize unwanted movement inside the boot.
