Lagoon Blue Performance Compression Socks
Engineered for endurance athletes seeking medical-grade graduated compression (20-30mmHg) to boost oxygen delivery during marathons, triathlons, or mountain bike adventures. The 4″ structured ankle cuff stabilizes high-impact movements while remaining discreet under workout gear.
Key Performance Features:
✅ Dynamic Y-Heel System – Patented contoured heel pocket reduces slipping by 40% compared to flat-seam designs
✅ Thermo-Regulating Mesh – 37% ventilation zones keep feet 5°C cooler than standard compression socks
✅ Silent Toe Technology – Zero-itch seamless toe construction prevents friction burns during 10+ hour wear
Crafted from ultra-lightweight Olefin fibers (85gsm density) that evaporate sweat 3x faster than cotton blends – ideal for cyclists tackling 100-mile routes or runners training in 90°F heat. The USA-made construction includes reinforced stress points at the heel and ball-of-foot zones for extended durability.
