Advice for Trail Runners: The Nike Men's Ultrafly Trail Racing Shoes help you run faster on trails. Developed with elite Nike Trail athletes, these are Nike's pinnacle off-road innovation. 

Underfoot Feel

The Nike Ultrafly Trail Racing Shoes midsole features ZoomX foam with a carbon fibre Flyplate. The result? Lots of cushioning and propulsion - that should help you maintain your pace more comfortably.

Please note that the ZoomX cushioning has a fabric wrap to improve durability and make it resistant to abrasion.

In a bid to make you feel as confident as possible, the outsole uses Vibram's Litebase technology, along with Vibram Traction Lug. This lightweight rubber delivers exceptional levels of grip on both wet and dry terrain.

Stability over uneven terrain should be improved by a flat-bottom design. However, the heel-to-toe rocker is likely to offer smoother transitions and aid comfort on undulating terrain.

Upper Fit

The Vaporweave mesh in the Nike Ultrafly Trail Racing Shoes' upper should feel very breathable and light. Although, a classic collar construction, along with engineered zones of support, should translate into great support on uneven terrain. 

Ideal Run Type

The Nike Men's Ultrafly Trail Racing Shoes are for goal-orientated runners who want to achieve their best. Whether that's targeting a race win, or beating your previous personal best on a favourite route.

Given the level of grip and cushioning on offer, you can use these for long distance trail events.

Sizing Advice 

Shoe size is a personal preference and everyone's feet are different, but we want to ensure you avoid any pain or discomfort from bruised toenails, rubbing, blistering or pins and needles.

Your running shoes should have enough width to allow you to spread your toes and should have some space at the front (we recommend having a half to one thumb's width of space from the end of your longest toe to the front of your running shoes).

This usually means that your running shoe will be at least a half size bigger than your regular shoe size though this can vary from brand to brand.
