Despite Nike being best known for crafting advanced shoes for professional athletes, they do produce quite a range of running shoes for under $100. Ostensibly replacing the Run Swift, the Quest came out last year and quickly gained popularity, which brings us to 2019.
The sole unit on the Quest 2 is the same as the original, being made of Phylon (which is not quite as soft as Cushlon, the cushion used in several performance running models), Nike’s patented version of injection-molded EVA. It’s light and semi-responsive, being overall pretty comfortable. It provides a nice blend of springiness and durability, while being pretty flexible.

The upper as roomy and flexible, unlike something like the Downshifter, which leans towards the stiff side. However, it does retain the warmth of the Downshifter and Run Swift. The upper includes Flywire for a more secure fit, but otherwise has no features of note.
The Nike Quest 2 is a fine shoe for $70, although the Asics Cumulus 20 is on sale for the same price. No frills, the Quest is adequate as a cheap trainer for normal day wear, a casual run, or perhaps if you have a child in extracurriculars.
