@thehybridmiles: A few weeks back Kiplimo ran a world record half marathon (57:20) in a prototype of the Nike Alphafly 4. Using those leaked images I've managed to mock up what the shoe has the potential to look look like for its release later this year. Key Difference: Mid Sole ☁️ It looks like we'll be getting more Zoom foam to provide more of a cushioned ride. Ideal for the marathon distance. The Stack ⬆️ The stack on the shoe seems to be a lot higher meaning this will be even of a high level shoe & beginners should be careful with risk of injury. What else to expect: - A lighter shoe - More of a responsive ride - & hopefully more durability Will you be trying the Alphafly 4 when they drop this year? #nikealphafly4 #alphafly #nikerunning #runningshoes @Nike @HYROX
