Asics Metaspeed Sky Tokyo vs Adidas Adizero Adios Pro Evo 3:
Which to Choose

Start with the number that jumps out: weight. The Sky Tokyo comes in at a very light 163g (men's US 9), but the Adios Pro Evo 3 is in another category entirely at roughly 99g — one of the first racers to break the sub-100g barrier. That gap is the defining difference between these two shoes. Stack and geometry are otherwise a near-match: the Sky Tokyo measures about 39mm heel / 33mm forefoot and the Evo 3 about 38mm / 32mm, and both carry a 6mm measured heel-to-toe offset (Asics states 5mm, adidas markets 3mm), so you sit at a similar height with a similar forward tilt in either. The real mechanical divergence is how each handles the carbon. The Sky Tokyo uses a full-length carbon plate sitting in FF Leap (A-TPU) foam, which gives a firmer, race-edged, distinctly snappy transition that rockers you toward your toes — propulsion you can feel pushing back. The Evo 3 skips the full plate for a carbon-infused U-shaped ENERGYRIM perimeter stiffener wrapped around its lowest-density Lightstrike Pro Evo foam, and the ride reads as plusher and springier underfoot, a PEBA-class rebound that snaps forward when you're moving quickly rather than the firmer pop of the Asics. Both are neutral and narrow, but stability is a weakness for each and slightly worse on the Evo 3 (1/6 vs the Sky's 2/6) — its taller, ultra-thin, featherweight platform feels tippy the moment you slow down and punishes sloppy form. Durability favors the Asics only in relative terms: its MOTIONWRAP upper and thin build already sacrifice longevity for speed, but the Evo 3's paper-thin mesh and stripped, ultralight construction are famously short-lived, built for a handful of key races rather than a season of workouts. Both excel from the half up to the marathon and both reward the same fast, forward-leaning stride; neither does anything well at easy jogging pace.
