#243 Between Two Feet: Nike Vaporfly 4 and the Impact of Geometry Changes to a Shoe

If you've been following us for a while, you know that Matt & Andrea often experience shoes completely differently, so on this episode they get together to compare & contrast their experiences in Nike's major overhaul to the OG of supershoes: the Vaporfly 4. With a shorter stack height and narrowed down platform, this nimble racer offers a vastly different ride from its big sibling, the Alphafly 3. Andrea loved Vaporfly 3, so how will she feel about the updates? Matt's often found the Vaporflys too unstable, so will that continue? Tune in to see if you side more with Andrea or Matt!
