My Buying Guides on Nike Free Rn Flyknit 2018

When I first looked at the Nike Free RN Flyknit 2018, what stood out to me was how lightweight and flexible it felt. The Flyknit upper gave it a snug, sock-like fit, and I immediately noticed that it looked like a shoe built for natural movement rather than heavy support. If I wanted a running shoe that feels easy on the feet for short to moderate runs, this one quickly became interesting to me.
What I Like About It
One of the biggest reasons I would consider this shoe is the comfort. The Flyknit material wraps my foot nicely and gives a breathable feel, which is great if I run in warm weather. I also appreciate the Free sole design because it allows my foot to move more naturally. For me, that makes walking, gym sessions, and casual wear feel comfortable too.
Fit and Sizing
From my experience, fit is something I would pay close attention to with this model. The Flyknit upper tends to feel snug, so I would make sure I choose the right size carefully. If I have wider feet, I might want to try it on first or consider sizing up slightly. I found that getting the right fit matters a lot because the shoe is designed to hug the foot closely.
Performance for Running
If I’m using this shoe for running, I would see it as best suited for short runs, treadmill workouts, and light training. I like that it feels flexible and responsive, but I wouldn’t choose it if I needed maximum cushioning for long-distance runs. For me, it works better as a natural-feel trainer than as a heavy-duty marathon shoe.
Comfort for Daily Wear
I also think this shoe works well beyond running. I could wear it for errands, travel, or everyday walking because it feels light and easy on my feet. The style is simple and sporty, so it fits well with casual outfits. My experience tells me that a shoe like this is useful if I want both performance and lifestyle comfort in one pair.
Durability and Build Quality
When I buy running shoes, I always think about how long they will last. The Nike Free RN Flyknit 2018 feels well-made, but because it is lightweight and flexible, I would not expect it to be as rugged as more structured trainers. For my use, I would see it as a shoe for moderate wear rather than very intense daily mileage.
Who I Think It Is Best For
I would recommend this shoe to someone who wants a light, flexible, and comfortable option for short runs or casual wear. If I prefer a natural ride and a close fit, this model makes sense. However, if I need lots of arch support, extra cushioning, or stability, I would probably look at another shoe.
My Buying Tips
Before I buy the Nike Free RN Flyknit 2018, I would check:
- My exact size, especially if I have wider feet
- Whether I want it mainly for running or casual wear
- How much cushioning I prefer
