The Nike Free RN line has consistently been a popular choice for runners seeking a balance between minimalist feel and supportive cushioning. The model identified as 880839-001, often referred to as a "successor model" or "follow-up" to previous iterations, represents a specific design within that lineage. This article will delve into the specifics of this particular Nike Free RN shoe, focusing on its design features, performance characteristics, and its position within the broader Nike Free RN family. We'll also explore the listing details provided, analyzing the price and seller information.
Understanding the Nike Free RN Lineage:
Before examining the 880839-001 model in detail, it's crucial to understand its place within the Nike Free RN evolution. The Nike Free technology itself was born from the idea of mimicking barefoot running, offering a flexible and natural feel. Early iterations focused heavily on this minimalist approach, prioritizing flexibility over significant cushioning. However, as the line evolved, Nike incorporated more sophisticated cushioning systems and supportive elements to cater to a wider range of runners and running styles.
Each subsequent model in the Free RN series, like the RN 2017, RN 5.0, and beyond, typically featured refinements in areas such as:
* Cushioning: The evolution involved improvements in the foam midsole, often using newer materials for enhanced shock absorption and energy return. Earlier models leaned towards a thinner, more minimalist sole, while later versions offered more substantial cushioning without sacrificing the inherent flexibility of the Free technology.
* Flexibility: While the core principle of flexibility remained, the design and placement of flex grooves in the outsole were often refined to optimize the natural movement of the foot during the gait cycle.
* Upper Construction: The upper, responsible for the fit and breathability of the shoe, underwent changes in material choice and construction techniques. This included the use of different mesh fabrics for improved ventilation and a more comfortable, sock-like fit.
* Support: Later models often incorporated elements for enhanced support, such as strategically placed overlays or engineered mesh patterns, to provide better stability and secure the foot within the shoe.
Nike Free RN 2017 'Black' (880839-001): A Closer Look
The Nike Free RN Run in black and white, with the style code 880839-001, is widely identified as a variant of the Nike Free RN 2017. While Nike doesn't explicitly label all models as direct "successor" models, the iterative design process indicates that this particular 880839-001 version builds upon the features and improvements introduced in the 2017 model.
This black and white colorway is a classic and versatile option, suitable for various running environments and personal styles. The black base provides a sleek look, while the white accents add contrast and visual interest. The exact materials used in the upper might vary slightly depending on the production batch, but generally, the 2017 model utilizes a breathable mesh for comfort and ventilation.
The midsole likely employs a lightweight foam, offering a balance between cushioning and responsiveness. The outsole features strategically placed flex grooves that enable a natural range of motion, allowing the foot to bend and flex as it would barefoot. The level of cushioning in the 2017 model would likely be a step up from the earlier, more minimalist Free models but still less than the maximum cushioning found in some of Nike's other running shoes.
