The Spiro Compression Calf Sleeve combines therapeutic support with athletic performance enhancement. Crafted from super-soft, quick-dry breathable fabric, it maintains a thin, lightweight construction that maximises heat emission—essential for maintaining comfort during extended wear and intense activity. The graduated compression rating of 15-20mmHg applies consistent, therapeutic pressure around the entire calf, effectively absorbing the shockwave impact that travels through muscles, veins, and joints during running and high-impact sports. This compression mechanism actively increases blood circulation, accelerating oxygen delivery to working muscles whilst reducing lactic acid accumulation—the primary driver of muscle fatigue and post-exercise soreness. Beyond performance benefits, the sleeve provides targeted relief and prevention for common calf-related issues including poor circulation, cramping, shin splints, and general sports-related pain. The seamless 360° knit construction eliminates chafing points and delivers uniform compression without restrictive seams, whilst the shaped-to-fit design respects your calf's natural contours for unrestricted movement. Tag-free construction ensures irritation-free wear, and the sleeve pulls on and off effortlessly. Additionally, the improved blood flow benefits extend to air travel, making this sleeve valuable for both athletes and frequent travellers seeking circulation support and injury prevention.
