For me, this shoe gives off a clean, sporty style that works well both for workouts and casual wear.
Why I Considered Buying It
I was drawn to this model because I wanted a shoe that felt comfortable for daily use but still performed well during runs and training sessions.

The Nike Free Run Flyknit 2018 seemed to check those boxes, especially if I wanted something that could handle short runs, walking, and gym sessions.

Durability and Build Quality
When I buy shoes, I always look at whether they can handle regular use. The Nike Free Run Flyknit 2018 feels well-made, but I would still expect the Flyknit upper and flexible sole to show wear faster if I use them very aggressively. In my opinion, this shoe is best for someone who wants everyday versatility more than maximum rugged durability.
