The Simms x Sealskinz Rangeley Merino Waterproof Sock – Mid combines the expertise of two premier outdoor brands to deliver the ultimate defense against cold, wet feet. Designed for anglers who face unpredictable weather or compromised wading gear, this sock functions as a completely waterproof barrier that fits comfortably inside wading boots or hiking shoes. It provides a critical layer of protection for wet wading in cooler temperatures or ensuring dry feet during long days in heavy rain.

Best For

This product excels in wet wading scenarios where water temperatures are low enough to require insulation but high enough to forego full waders. It is also an invaluable tool for anglers wearing older waders with pinhole leaks, acting as a secondary waterproof skin to keep socks dry despite gear failure. The mid-length cut makes it highly practical for rainy boat days or hiking through wet, tall grass where moisture typically wicks down into standard footwear.

Key Features

• Three-Layer Waterproof Construction A hydrophilic membrane is bonded between the inner and outer layers, blocking external water completely while allowing internal moisture and sweat to escape.
• Hydrostop Technology An elastic taping around the inner cuff creates a barrier against the skin, significantly reducing the risk of water trickling down the leg during heavy downpours.
• Seamless Design Hand-linked toe seams and a four-way stretch prevent bunching and friction points, eliminating blister hotspots during long hikes to the river.

Why We Like It

We appreciate this sock because it solves the clammy sensation often found in lesser waterproof footwear. The proprietary bonding process ensures the layers move as one, providing the stretch and tactile feedback necessary for navigating slippery river bottoms. By integrating the waterproof membrane directly into a knit sock structure, it offers the dexterity of a standard hiking sock with the performance of a neoprene bootie, making it a versatile piece of kit for anyone who refuses to let wet feet shorten their fishing trip.

Fabric / Material Composition

The sock features a durable outer layer made of a Polycolon and nylon blend designed to withstand abrasion from boot interiors. The functional core is a waterproof, breathable membrane, while the inner liner utilizes Merino wool to regulate temperature and manage moisture buildup next to the skin.
