Adjustable External Sealing System

Designed specifically for wet environments, PROSHIELD features a removable external adjustable sealing strap around the sock opening. Once secured, it creates a snug seal that helps prevent water from entering from above—even when the sock opening is fully submerged. This makes PROSHIELD suitable for deeper river crossings, wading, marshes, snow, and other demanding wet conditions.

Adjustable Cuff Seal Technology

An reusable, removable and adjustable waterproof strap at the sock opening helps prevent water from entering from above—a common weak point of waterproof socks. Secure the strap around your calf for a snug seal that provides added protection when wading through streams, marshes, wet grass, or snow.

A warm inner of 64% Merino Wool and 24% acrylic helps regulate temperature in cold, wet conditions. Merino Wool naturally manages moisture while retaining warmth, helping keep your feet warm and comfortable when conditions turn harsh.

Activities

Designed for fly fishing, hunting, motorcycling, heavy rain, and professional work in wet areas. PROSHIELD is a lightweight, flexible option for situations where full waders aren't necessary, providing reliable weather protection while allowing greater freedom of movement.

Built for Water Crossings. Not for Swimming or Diving.

PROSHIELD features an external adjustable sealing strap designed to keep the sock opening securely sealed—even when fully submerged. It is built for river crossings, wading, and other outdoor activities where the socks may be completely immersed.

Not recommended for swimming or diving. These activities expose the sock opening to continuous lateral water movement and direct water flow around the seal. This is different from the water exposure encountered during wading and may increase the risk of water entering through the opening.
