NK Ultrafly Trail orange white black blue EU 36-45

The NK Ultrafly Trail in orange, white, black, and blue is a high-performance trail running shoe engineered for serious off-road athletes. Designed with a carbon-fiber Flyplate and a supercritical foam midsole, this sneaker delivers explosive propulsion on steep climbs and rugged descents. The aggressive Vibram outsole with 4mm lugs provides exceptional grip on loose dirt, mud, and rocky terrain, making it ideal for ultramarathon distances and technical trails. The breathable, reinforced upper offers a secure, locked-in fit while shedding water and debris. Available in EU sizes 36 to 45, the Ultrafly Trail combines NK's racing DNA with trail-specific durability. Whether you happen to be tackling mountain paths or forest singletracks, this shoe ensures stability and speed. The striking colorway—orange, white, black, and blue—ensures high visibility on the trail. Perfect for trail runners seeking a carbon-plated racing shoe for competitions or fast training sessions. Experience responsive cushioning and superior traction with every stride.

How to Style It

The trail heritage of the NK Ultrafly Trail means athletic pieces - track jackets, mesh shorts - look intentional rather than costume-like.

If you rotate sneakers weekly, the NK Ultrafly Trail slots into a three-shoe rotation without clashing with the rest of your closet.

For a clean everyday look, wear the NK Ultrafly Trail with tapered trousers and a plain tee, and let the colors do the talking.

Everyday Use

For people on their feet all day, the NK Ultrafly Trail keeps the pace with cushioning that survives eight-hour shifts.

Runners use the NK Ultrafly Trail for easy days and gym sessions, while the outsole holds up to regular pavement work.

The NK Ultrafly Trail is a strong first replica pick too: the silhouette is iconic, the fit is forgiving, and the orange, white, black and blue colorway matches nearly everything.

Comfort & Fit

The NK Ultrafly Trail works for wide feet better than most because the toe box keeps its structure instead of squeezing inward.

Flex grooves in the outsole let the NK Ultrafly Trail bend naturally at the toes, so your stride never feels fought by the shoe.

The interior lining of the NK Ultrafly Trail is smooth and seamless around the toe box, so sensitive feet stay comfortable.

Design & Materials

Every seam on the NK Ultrafly Trail sits flat against the foot, which means fewer hot spots during long days on your feet.

Lacing on the NK Ultrafly Trail runs smooth through eyelets and holds a knot all day without constant re-tightening.

Underfoot, a cushioned midsole absorbs impact and returns a little bounce, which is exactly what you want from a daily trail sneaker.

Sizing Guide

The lacing system on the NK Ultrafly Trail lets you fine-tune the midfoot, so a slightly loose fit can be locked down in seconds.

Compared with other trail sneakers, the NK Ultrafly Trail needs no sizing adjustment - order your usual EU size.

Insoles in the NK Ultrafly Trail are removable, so swapping in a sport or orthotic insole is straightforward.
