Advice for Road Runners: The Nike Women's Alphafly 3 Road Racing Shoes should meet the needs of both elite and everyday marathon runners. 

Information gathered from the largest-ever women's testing pool for a Nike Racing Shoe helped improve the design of the latest edition. 

Underfoot Feel

Fully-connected ZoomX foam offers smoother transitions and comfort for heel, mid, and fore-foot strikes. The ultra soft and bouncy foam feels incredibly cushioned and protective - perfect for long distance efforts.

As you start to apply force to the midsole, you should start to experience the propulsive effect of the full-length carbon fibre Flyplate kick into action. This has also been wider in the midfoot to offer more support than before.

The final propulsive component is the dual Air Zoom Units in the forefoot. This technology puts the Nike Alphafly 3 Road Racing Shoes in a league of their own when it comes to energy return. This is because the Air Zoom Units compress and spring back - launching you onto the next step. 

An updated Fast Shot outsole delivers great traction and grip. 

Upper Fit

The Nike Alphafly 3 Road Racing Shoes feature an updated AtomKnit 3.0 upper that offers more breathability and midfoot support. However, softer yarns in the upper should feel less rigid than before. 

As the upper can accommodate foot swelling too, the chances of friction are significantly reduced. An essential attribute of great marathon running shoes. Finally, lofted Flyknit heel pods hold your ankle securely in place. 

Ideal Run Type

The Nike Women's Alphafly 3 Road Racing Shoes deliver the ultimate competitive advantage on race day. Especially when you're running a marathon. 

It's very likely that they'll improve your race time finishing time and keep you feeling fresher for longer.

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.
