## Summary description

## Long description

Buff Coolnet Quarter Socks 137788901 in black for EU size 42–44 are lightweight quarter-length sports socks designed for active use. Constructed from breathable Coolnet fabric, these socks focus on ventilation and moisture management to keep feet cooler and drier during exercise. The low-cut ankle profile and snug fit provide a secure feel without excess bulk, making them suitable for running, gym sessions, hiking and everyday wear.
Advantages
These socks combine a light construction with targeted breathability to reduce overheating and sweat accumulation. The Coolnet fabric enhances airflow across the foot, while the quarter height protects the ankle area without adding unnecessary material. A fitted design ensures the sock stays in place during dynamic movement, and the black colour offers a neutral option that pairs with most sports footwear.
Suitable for
 Running and interval training
 Gym workouts and fitness classes
 Day hikes and outdoor activity
 Casual everyday wear under low-profile shoes
Key specifications
 Size range: European 42–44
 Length: quarter / low-cut ankle profile
 Primary material: breathable Coolnet fabric for ventilation and moisture control
 Colour: black
 Fit: snug, anatomical fit to minimise slipping
 Weight: lightweight construction suitable for high-activity use
How to use
Put the socks on so the heel aligns with the sock’s heel zone and smooth any folds to ensure the anatomical fit sits correctly around the arch and ankle. Use them with appropriate sports shoes for the intended activity — running shoes for runs, trainers for gym sessions, and hiking shoes for outdoor walks. After use, follow the garment care instructions on the product label to preserve fabric performance and fit.
Usage recommendations
For best results in high-intensity sessions, pair these breathable quarter socks with moisture-wicking footwear and consider alternating pairs to allow each pair to dry fully between uses. Wash with similar colours at the recommended temperature and avoid fabric softeners to maintain Coolnet fabric effectiveness.
