Sizing Wear & Care

For the perfect fit, take a quick measurement of the widest part of your calf. Our compression socks are expertly designed to provide the ideal level of compression for their purpose. If your calf measurement is between sizes, go with how you prefer your compression socks to feel. If you prefer a firmer compression, go with the smaller size.

Care & Maintenance Guide

Proper care ensures your BIOSx compression socks last longer and continue delivering maximum comfort and performance.

Washing Instructions:

For best results, hand wash after each use to maintain durability.
Prefer machine washing? Use a gentle warm cycle (max 30ºC) with similar colours.
Bonus points for placing them in a mesh laundry bag and selecting the hand-wash setting.

Drying Tips:

Avoid wringing them out—give them a gentle squeeze to remove excess water.
Air drying is ideal, but if you’re in a pinch, tumble dry on low heat (below 30ºC).
Pro tip: As socks age, a short tumble-dry session can help shrink the elastic fibers and restore optimal compression.
Never dry in direct sunlight or on heaters/radiators—this can damage the elastic fibers.

Detergents:

Stick to mild detergents only.
Avoid fabric softeners and never use bleach.

Compression Lifespan:

Over time, elastic fibres naturally wear down. Replace your socks at least every 6 months to maintain proper compression and support.

About the BIOSx Rapid Recovery Compression Socks - Black

Serious recovery starts here. BIOSx Rapid Recovery Compression Socks use medical-grade compression and advanced infrared yarns to accelerate muscle repair, reduce soreness by up to 61%, and fight fatigue. Engineered for high-performance athletes, they deliver the edge your body needs to recover smarter—not just harder.

Key Features

Infrared-Activated Cellular Recovery

Powered by advanced infrared fibre technology, BIOSx harnesses your body’s natural heat to generate infrared energy—boosting circulation, accelerating healing, and promoting cellular regeneration. This process increases ATP production (your cells’ energy source), helping muscles recover faster, reduce inflammation, and perform at their peak.

Graduated Compression for Circulation Support

Boosts oxygen-rich blood flow to reduce lactic acid buildup, speed up recovery, and minimise next-day pain.

Zoned Cushioning & Seamless Fit

Shock-absorbing heel and toe padding reduce impact without bulk. Mesh panels provide airflow; comfort welt and seamless toe ensure irritation-free wear.

Fresh-X™ Moisture Management

Ultra-wicking yarns pull sweat away fast, keeping your feet cool, dry, and odour-free—no matter how hard you go.

Targeted Arch & Plantar Fascia Support

Designed to provide firm, anatomically aligned compression through the arch and plantar fascia—helping reduce foot fatigue, improve alignment, and support every step during recovery.

Cramp & Shin Splint Defence

Supports key muscle groups to reduce the risk of cramps, fatigue, and shin pain during intense activity.

Compression Rating

Firm 25-28 mmHG

Compression Guide
