Nike Zoom Rival Fly 4 - Obsidian/Persian Violet/Green Abyss/White - FV6040-401

While comfortable for shorter to mid-distance runs, the Zoom Rival Fly 4 is primarily designed for speed and shorter races. For marathons, consider models with more substantial cushioning and support.

There should be about a thumb's width of space between your longest toe and the end of the shoe when standing. The heel should feel secure without slipping.

Yes, they can be used for general gym workouts, but they are optimized for running. For lifting or cross-training, shoes with a flatter, more stable sole might be preferable.

The main color of this specific model is Obsidian (Black), with accents of Persian Violet, Green Abyss, and White.

Regularly clean with a damp cloth, allow to air dry, and store in a cool, dry place. Avoid machine washing.

The Zoom Rival Fly 4 generally offers a standard width fit. If you have significantly wide feet, you may find them snug. Trying them on or checking reviews specific to width is recommended.

Ensure laces are adjusted properly. Try different lacing techniques to optimize lockdown and comfort. Ensure you have the correct size.

While the outsole offers good traction, extreme wet conditions can reduce grip. Exercise caution and consider shoes with specialized wet-weather tread if this is a frequent concern.

Cushioning and responsiveness can decrease with heavy mileage. This is normal wear and tear. Consider replacement after significant use.
