Professional Grade Gradient Compression Ski Socks - Crafted with high quality composite wool fibers, these socks not only possess excellent heat retention and warmth with moisture wicking and breathability properties, but also present a fashionable color. The body of the sock uses a unique pressure gradient technology that naturally transitions from dark blue to light gray, symbolizing the combination of strength and elegance. The gradually increasing pressure from the arch of the foot to the calf effectively promotes blood circulation and significantly reduces leg fatigue. The multi-point cushioning layer, interwoven with various color schemes, provides extra protection for your legs, enhances the cushioning ability, and significantly reduces the impact during exercise. Wearing these colorful and functional ski socks, whether you are skiing or running, will allow you to focus more on outdoor sports and significantly improve your sports performance.
