🧪 Premium Materials
Every LEO Crew Sock is crafted with a performance-grade blend designed to keep your feet comfortable through long shifts and high-intensity situations:
Nylon for durability and structure
LYCRA® Spandex for a secure, contoured fit
FYnesse® STA-COOL® Polyester to prevent blistering
CuTECH® copper-infused fiber to enhance circulation and reduce bacteria
Silver Tech Anti-Microbial to fight foot odor and infection inside and out
💪 C4 Technology — The Ultimate Performance Sock
Developed by the FirstOn R&D Team, C4 Technology delivers four layers of performance in every pair:
Comfort — A stay-put comfort band keeps the sock in place, even in "hungry boots"
Contouring — Graduated compression contouring prevents swelling during long shifts
Compression — Strategically placed compression supports your ankles, legs, and arch
Cushioning — Extra padding in the heel, ball of foot, and ankle reduces impact and friction
