adidas Adizero Prime X3 STRUNG vs Li-Ning Feidian 6 Ultra

The Li-Ning Feidian 6 Ultra and adidas Adizero Prime X3 STRUNG are both unconventional super shoes with unusual plate setups. The Li-Ning feels more like a pure race-day shoe: it's lighter, softer, and bouncier, with an asymmetric two-tier carbon plate that gives the platform structure while leaving a void under the midfoot. That makes it feel highly propulsive if you load the heel or forefoot cleanly, but less forgiving if you land through the middle of the shoe. The adidas is less nimble and not especially light, but it feels better suited to steady long runs, progression efforts, and fast cruising. It features a carbon plate paired with some carbon rods for added snap and structure.
