Cushioning Level Close Cushioning level, or stack height, refers to how much shoe is between your foot and the ground. For this category, we reference the amount of cushioning below the forefoot as the heel height will be equal to or greater than the forefoot height. Learn more about stack heights and how we measure them. Barefoot 0-13mm. The Shoe generally does not have a midsole and feels like there is no cushioning. This shoe is all about feeling the ground underfoot. Minimal 14-18mm. The shoe has a thin midsole that allows for a natural running experience. Racing shoes and minimalist shoes are common here. These shoes offer a feeling of being connected to the road or trail. Low 19-23mm. The shoe has a slightly cushioned feel and may feature added cushioning technologies. Performance training shoes and some trail shoes are common here. These offer protection during footstrike but prioritize a lightweight, grounded experience. Medium 24-28mm. These shoes have a stack height that fall near the middle of the spectrum.The shoes in this category are verstaile and great for all types of runs and distances. High 29-34mm. The shoe has a thick midsole and ample cushioning. These shoes are highly protective and absorb more impact than the body. Maximal 35mm plus. The shoe has an extremely thick midsole and extra cushioning. The focus is on protection and soft foam underfoot with hardly any ground feel. Stability Level Close Neutral Running Shoes Neutral shoes support the foot through a normal range of arch collapse and generally do not have a built-in technology to correct movement. Stable Stability shoes are a great option for those who overpronate or need added support. These shoes help to limit the inward rolling motion of the ankle while running or walking and assist in guiding the foot straight through the gait cycle. Product Details: All of the best marathon racing shoes have a unique feature that sets them apart from the rest, but none of them embodies uniqueness and innovation quite like the Nike Alphafly 3. Just by looking at it, you can tell that it's a fast and special shoe. No detail has been overlooked, and Nike has delivered another surefire racing shoe that's bound to be seen on many runners' feet on marathon courses throughout the world. Although this shoe stands out in every way, the star of the show is the midsole design. For the first time in the Alphafly series, the midsole now features a continuous bottom layer of ZoomX cushioning. This promotes smoother transitions and increased propulsion while still offering an incredibly soft ride. Sandwiched between the top and bottom layers of ZoomX foam lie the quintessential staples of the Alphafly — the two Air Zoom units and carbon fiber Flyplate. These elements work together to launch you into your next step, making running faster feel easier.For improved stability over long distance runs, the full-length carbon fiber Flyplate has been widened, which also helps deliver a more propulsive sensation underfoot. Additionally, the Alphafly 3 has a widened base, which makes it more accommodating for the non-elites who still want to experience the top-end speed this shoe brings to the table. With increased speed comes the need for confidence-inspiring traction, and the Fast Shot outsole balances the need for grip without compromising weight. Meanwhile, the updated Atomknit 3.0 upper dials in the fit and keeps your feet comfortably secure from start to finish. Overall, the Nike Alphafly 3 continues its legacy as a pinnacle marathon racing shoe that is bound to etch its name in the story of your best race. Model Number: FD8311-104
