【20–30 mmHg Graduated Compression – Targeted Leg Support】Firm compression starts at the ankle and gradually decreases up the leg, helping to improve blood circulation, reduce tired, heavy legs, and relieve mild to moderate varicose veins, swelling, or muscle soreness. Ideal for long periods of standing or sitting. 【Cooling & Breathable – All‑Day Comfort】Made from 80% polyamide and 20% Lycra elastane, these socks feel cool to the touch and stay breathable in hot weather. The lightweight, moisture‑wicking fabric keeps feet dry, reduces chafing, and delivers secure compression without being too tight. 【Ergonomic Design – Better Support, Less Fatigue】Featuring an ergonomic toe box for natural toe movement, targeted Achilles tendon support, and a specific calf compression zone. This design helps reduce muscle vibration, improve blood flow, and provide focused support where your legs need it most – ideal for post‑workout recovery, long shifts, or daily wear. 【All-day Comfort & Travel Essential – 2 Pairs】Great for long flights, nursing shifts, office work, teaching, pregnancy, running, and walking. Two pairs allow easy rotation – wear one while washing the other. A reliable companion for travel, work, and active daily life. 【Size Guide – Choose Your Fit】Measure your calf (widest part) in cm. If between sizes, choose the smaller size for better compression, or larger size for a lighter feel.– S/M: calf 28–38 cm (UK shoe 3–8); L/XL: calf 35–45 cm (UK shoe 8.5–14)
