Introducing the new Prototype PB Sock — The Prototype Project
Born from a newly engineered weaving structure, this prototype enhances breathability and reduces weight without losing the PB grip you rely on. Designed to move through air with less resistance and more intention.
• Compression Designed — Promotes healthy blood circulation to reduce injury risk and sustain peak performance longer.
• Elastic Strap — Prevents folding and twisting, protecting your skin from irritation and blisters.
• Anatomically High Padding & Ankle Cushioning — Delivers targeted support and comfort across any distance.
• Breathable & Light — Advanced lightweight weave wicks moisture quickly, keeping you dry and fresh even in warmer weather.
• Seamless Weaving — Smooth, irritation‑free construction for maximum comfort.
