Nike Free RN 2018 Trainers - Black/Gold - UK 6.5

While lightweight and comfortable, the Free RN 2018 is best suited for shorter to medium distances due to its minimalist cushioning and support. For marathon distances, consider trainers with more substantial cushioning and support.

These trainers are primarily designed for road running and general training. The outsole pattern may not provide adequate grip or protection for uneven or technical trail surfaces.

If you enjoy a natural stride, have strong foot muscles, and are looking to improve your ground feel, these could be a good fit. If you are new to minimalist footwear or have concerns about foot strength, a gradual transition is recommended.

The Free RN 2018 is characterized by its highly flexible, natural motion sole, offering a more barefoot-like experience. Other Nike running shoes often feature more structured support, advanced cushioning systems, or specific designs for different types of running.

The sole is designed for durability in key high-wear areas with strategic rubber placement. However, the extreme flexibility means care should be taken to avoid excessive abrasion or damage from sharp objects.

'RN' typically stands for 'Run', indicating its primary intended use as a running shoe within the Nike Free line.

Adjust the lacing system. Try different lacing techniques to achieve a more personalized fit. Ensure you are wearing appropriate athletic socks.

The Free RN sole is designed for natural motion; grip on extremely wet or slick surfaces may be reduced compared to shoes with aggressive tread patterns. Use caution in such conditions.

Ensure the shoes are air-dried naturally. Avoid using heat sources, which can make the sole materials temporarily stiff. They should regain flexibility with use.
