What are the best socks for marathon running?

Accapi Marathon infrared run socks combine three performance technologies — infrared fiber for enhanced circulation, EQT Equilibrium Technology for improved running form and proprioception, and AEC Adaptive Ergonomic Compression for muscle support and reduced fatigue. Available in ankle, 1/4, and knee lengths for every distance and condition.

Do infrared running socks help with fatigue?

Yes — Accapi infrared running socks continuously improve circulation and muscle oxygenation, reducing foot fatigue and in-shoe swelling during running. AEC compression further reduces muscle oscillation and soreness — helping you run further with less fatigue.

What length running sock should I choose?

Accapi Marathon run socks are available in three lengths. Ankle length is ideal for warm conditions and shorter distances — it features a unique Protective Flap for blister protection on long runs. Quarter length suits most training and racing conditions. Knee length provides maximum coverage and compression support for long distances and recovery.

Are Accapi run socks good for triathlons?

Yes — Accapi Marathon infrared run socks are ideal for triathlon. The infrared fiber supports circulation and reduces fatigue across all three disciplines, while AEC compression minimises muscle oscillation and soreness. The precise ergonomic fit stays in place throughout the race.

What is EQT technology in a running sock?

Accapi's EQT Equilibrium Technology is tuned to your body's natural equilibrium — improving stability, balance, and proprioception during running. Better body awareness means improved running form, increased agility, and more efficient movement — particularly beneficial over long distances.

Collection: Infrared Fiber Run/Fitness Socks

Run Further. Train Harder. Recover Faster.

Accapi infrared run and fitness socks combine three powerful performance technologies in one technically advanced sock — making them the most capable run sock in the Accapi lineup. Available in ankle, 1/4, and knee lengths for every runner, every distance, and every activity.

Infrared Fiber — Enhanced Circulation & Less Fatigue
Accapi's infrared fiber absorbs your body heat and reflects it back as Far Infrared energy — continuously improving circulation, enhancing muscle oxygenation, improving thermoregulation, and reducing foot fatigue and swelling mile after mile.

EQT Equilibrium Technology — Better Form, Better Feel
Accapi's proprietary EQT technology is tuned to your body's natural equilibrium — improving stability, balance, and proprioception for better running form, increased agility, and greater body awareness throughout your run.

AEC Adaptive Ergonomic Compression — Maximum Support
Light AEC compression supports the foot and key muscle groups, reducing in-exercise muscle oscillation — minimising soreness, delaying fatigue, and helping you run longer and recover faster.

Precision Fit Construction
Reinforced heel and toe, flat toe cap junction, and accordion elastic forefoot band for a precise, ergonomic fit that stays in place from 5K to ultramarathon. The ankle length features Accapi's unique Protective Flap for enhanced blister protection on long runs.

Perfect for 5K, 10K, marathon, ultramarathon, triathlon, gym, CrossFit, and all fitness training.
