Adidas Adizero Adios Pro 4 vs Asics Metaspeed Sky Tokyo:
Which to Choose

October 4, 2026

Verdict

Both are elite marathon racers that will serve a sub-3:30/km runner superbly, so the decision rests on feel and footstrike, not quality. Go Asics Metaspeed Sky Tokyo if you want the lightest, firmest, most direct ride and you're a forefoot/midfoot striker focused on the half and full; go Adidas Adizero Adios Pro 4 if you want a softer, bouncier, more rockered ride with a touch more cushioned security and the flexibility to race anything from a 10K upward. When in doubt, the Sky Tokyo rewards a quick, efficient stride, while the Adios Pro 4 is the more versatile all-rounder.

Who Should Choose Each Shoe

Choose

Adidas Adizero Adios Pro 4

Choose the Adios Pro 4 if you want one racer that stretches from a 10K to a marathon and you prefer a softer, bouncier ride with a strong rolling rocker that does some of the work for you. Its slightly more forgiving pace range and more cushioned, secure landing make it the friendlier pick if you aren't exclusively a forefoot striker or want a bit more structure and guidance underfoot. It suits the runner who values a lively, planted, forward-tipping feel over shaving every last gram.

Choose

Asics Metaspeed Sky Tokyo

Choose the Metaspeed Sky Tokyo if your priority is the lightest possible race-day weapon and you want a firm, snappy, direct propulsion rather than a soft, rolling one. It's built for efficient forefoot and midfoot strikers who hold a quick turnover without lengthening their stride, and its FF Leap foam holds up especially well over the back half of a marathon. If the half and full are your target races and you want precision and agility over plushness, this is the one.

Head-to-Head

On paper these two look like twins — neutral support, low stability (2/6), the same top-end pace and responsiveness scores, low drops in the 5–6mm range, and "high but not maximal" cushioning — but they get there in different ways. The biggest hard-number difference is weight: the Metaspeed Sky Tokyo is dramatically lighter at 163g (men's US 9) versus roughly 201g for the Adios Pro 4, a gap of nearly 40 grams that you feel on every stride late in a race. The Asics also carries a touch more foam underfoot (about 39mm heel / 33mm forefoot) than the Adidas (around 36.6mm / 28.5mm), so it manages to be both taller and lighter. The plate architecture differs too: the Adios Pro 4 uses carbon-infused EnergyRods inside dual-layer Lightstrike Pro PEBA, which produces a softer, bouncier, pronounced rolling-and-tipping transition, while the Sky Tokyo pairs a full-length carbon plate with firmer FF Leap (A-TPU) foam for a snappier, more direct toe-off and cushioning that holds its shape deep into a marathon. In practice the Adidas feels cushier and more secure on landing with a stronger rocker that carries you forward, whereas the Asics feels firmer, more precise, and more agile, demanding a confident, centered footstrike. Both go tippy at easy jog speeds and only settle once you're moving fast. The other real split is range: the Adios Pro 4 is happy from the 10K through the marathon and has a slightly broader optimal window (to about 3:45 min/km), while the Sky Tokyo is a more single-minded half-and-full-marathon specialist tuned for runners who hold a quick, consistent cadence.
