The Merrell Siren 4 GTX Shoe is engineered specifically for women seeking unparalleled comfort, support, and stability on long hikes. Its key win is the combination of a GORE-TEX waterproof membrane for dry, breathable performance and a Vibram TC5+ outsole for exceptional traction across diverse outdoor terrains.

The Merrell Siren 4 GTX is built to perform in demanding outdoor environments. Its GORE-TEX waterproof membrane means you can confidently cross streams or hike in wet weather without worrying about soggy feet, while still allowing vapor to escape, preventing overheating.
On the trail, the Vibram TC5+ outsole is your reliable partner. Its specialized traction lugs grip firmly on a variety of surfaces, from loose gravel to muddy paths, and are designed to shed debris, ensuring consistent grip. This makes the Siren 4 GTX an excellent choice for diverse hiking trails, light backpacking, and general outdoor multi-sport activities.
Comfort for long distances is addressed by the FloatPro Foam midsole, which provides resilient, lightweight cushioning that helps reduce foot fatigue. The rock plate integrated into the sole offers crucial underfoot protection from sharp rocks and roots, allowing you to navigate rugged terrain with greater confidence. Furthermore, the bellows tongue acts as a barrier, preventing small stones, dirt, and other trail debris from entering the shoe, keeping your focus on the journey.
For those who spend extended periods on the trail, the NXT treatment helps manage odors, contributing to overall foot hygiene and comfort. The use of recycled materials across various components underscores Merrell's commitment to reducing environmental impact without compromising performance.
Setup:
Lacing: Ensure laces are snug but not overly tight. Adjust the lacing system to provide optimal support around your arch and ankle without creating pressure points. Experiment with different lacing techniques if you experience discomfort.
Socks: Pair your Siren 4 GTX shoes with appropriate hiking socks. Moisture-wicking synthetic or wool socks are recommended to enhance the shoe's breathability and waterproof performance.
Compatibility:
These shoes are specifically designed for women's feet, offering a tailored fit and support structure. While durable and versatile, their female-specific last may not provide the same optimal fit for men.
Ideal for hiking, trekking, light backpacking, and multi-sport outdoor activities across varied terrains, including wet and uneven surfaces.
Care:
Cleaning: After use, remove loose dirt and mud by gently brushing or rinsing the shoes with cool water. For stubborn dirt, use a soft brush and mild soap. Avoid harsh detergents or hot water, which can damage the GORE-TEX membrane and materials.
Drying: Allow shoes to air dry naturally in a well-ventilated area away from direct heat sources (e.g., radiators, direct sunlight). Removing the footbeds can aid in faster drying.
GORE-TEX Care: Do not use fabric softeners, bleach, or stain removers on the GORE-TEX membrane, as these can compromise its waterproof and breathable properties. If water repellency decreases, specialized GORE-TEX-compatible sprays can be applied.
Odor Prevention: The NXT treatment helps prevent odor. For additional freshness, ensure shoes are completely dry after each use.
