Understanding the Nike Free RN Lineage:
Before delving into the specifics of the Shield version, it's crucial to understand the heritage of the Nike Free RN line. The "Free" in the name refers to Nike's innovative approach to mimicking barefoot running. These shoes are designed to provide a natural, flexible feel, allowing for a more natural gait cycle and improved foot strength. The RN (Run Natural) designation further emphasizes this focus on natural movement and minimalist design. Previous iterations of the Free RN series have been lauded for their lightweight construction, breathable uppers, and exceptional flexibility, making them popular choices for everyday runners, particularly those who prefer a minimalist approach.
The Shield Upgrade: Weather Protection Without Compromising Performance:
The Nike Free RN 2018 Shield takes the core strengths of the Free RN line and adds a crucial element: weather protection. The key difference lies in the incorporation of a water-repellent upper. This isn't a completely waterproof design, but it offers significant protection against light rain, drizzle, and even some snow. The material used for the upper is carefully chosen to balance water resistance with breathability, preventing the build-up of sweat and ensuring comfortable wear even during intense runs.
The outsole also receives a significant upgrade in the Shield version. The rubber compound is designed for improved traction on wet surfaces. This is crucial for maintaining stability and preventing slips on slick pavements, muddy trails, or icy patches. The tread pattern itself is optimized for grip, offering a secure footing even in challenging conditions.
Design Features and Materials:
Let's break down the key design elements of the Nike Free RN 2018 Shield:
* Water-Repellent Upper: The primary feature differentiating the Shield from its non-weatherized counterparts. This upper provides a degree of protection against moisture, keeping your feet relatively dry in less extreme conditions.
* Breathable Mesh: While water-repellent, the upper still incorporates breathable mesh panels to prevent overheating and ensure adequate ventilation. This balance between protection and breathability is crucial for maintaining comfort during runs.
* Flexible Tri-Star Outsole: The signature Nike Free outsole design provides exceptional flexibility and a natural feel. The tri-star pattern enhances flexibility and adapts to the natural movement of the foot. In the Shield version, this outsole is made with a more durable, weather-resistant rubber compound.
* Low-Profile Design: The low-profile design keeps the shoe lightweight and allows for a close-to-the-ground feel, promoting a more natural running gait.
