✨ Key Features

Z-CROSS Cross-Binding System: Advanced structural elastic matrix wraps securely around the midfoot, inspired by athletic taping for a secure, supportive feel around the arch.
3D Lightweight Compression: Targeted, low-profile graduated compression designed for a snug, supportive fit without adding restrictive bulk or weight inside your racing shoes.
High-Visibility Reflective Strip: Sleek reflective strip on the sock cuff enhances visibility and adds a crucial layer of safety for early morning or night trail runs.
Merino Wool Sole & Eco-Tough Body: Natural Merino wool underfoot provides optimal thermal regulation and cushioning, paired with a resilient, moisture-wicking recycled nylon body that reduces environmental impact while offering exceptional tear resistance.
Reinforced Heel & Toe Protection: Level 2 localized medium cushioning at the high-friction heel and toe boxes dampens technical trail impacts and shields your feet from painful blisters.
