Adidas Adizero Adios Pro 4 vs ASICS Metaspeed Sky Tokyo

Ride profile: high cushion , neutral stability .

• Both reviewers rated the Adios Pro 4 as an excellent carbon racer that is softer and cushier than the Metaspeed Sky Tokyo, with a more protective heel landing. However, both preferred the ASICS for its lighter weight, poppier forefoot, and faster overall feel. The Adios Pro 4 is a strong value pick, especially at its lower price point.

  Ride:Updated Lightstrike Pro foam is softer and bouncier than the Pro 3, providing a cushier, more protective feel especially at the heel. Sharp rocker geometry delivers fast transition. Good energy return and springiness with no signs of foam degradation. Slightly more stable heel landing than the Metaspeed Sky Tokyo. The medial cutout may cause some instability concerns at slower paces. One reviewer noted it is improved over the Pro 3 but that the added softness comes with a slight stability trade-off.

  Fit:Runs short — both reviewers recommend going up half a size. The upper design has a lip near the toes that can catch toenails. Even accounting for US/UK size differences, it feels smaller than other Adidas shoes in the same size. Check centimeter sizing carefully. Rest of the fit around heel and midfoot is comfortable and secure.

  In their words: "a little bit softer" · "more comfortable for me and less aggressive" · "a great carbon shoe"

• BITR's preferred Adidas race shoe — beats the Pro Evo 2 at half the price.

  Ride:First Adios Pro where BITR likes the foam — v3 was too dense and firm. Lighter and more responsive in v4 with a propulsive feel and distinct pop off the toe. Traction is fine on dry pavement. Knocks out the NB SC Elite V5 in Megan's bracket.

  In their words: "almost feels blocky under foot" · "feels like slappy almost" · "more of a propulsive feeling"

• A light, soft and durable-outsoled racer that's aging well on price but suffers from a very soft ride, broken-rods durability issues, and an unstructured upper that makes it less reliable than the Pro 5 for marathons when form breaks down.

  Ride:Softer than the Endorphin Pro 5 and dulls quicker over time. Outsole is insanely durable, among the best in the comparison, with versatility despite minimal ridges. Foam softness caused the reviewer knee trouble around the 15-16 mile mark. Plagued by broken energy rods, likely because the softer Lightstrike Pro allows the rods too much movement.

  Fit:Minimal upper that lacks structure; some runners recommend sizing up half a size because the foot slides forward in the shoe, which can cause toe problems on a marathon.

  In their words: "insanely durable" · "minimal, but it does lack structure" · "a bit of knee trouble"

• Ben's marathon pick. Prioritizes cushioning over snappiness.

  Ride:Much softer than Pro 3 but plenty of cushion still. Carbon rods (not a plate) run under metatarsals, providing a softer ride ideal for the marathon distance. 200g men's 9 — heavier than his 5K/10K picks but weight matters less over 26.2. Ben ran 2:24 marathon PBs in both Pro 3 (Boston) and v4-style shoe (Valencia 2024). Very soft — ran 14:46 5K in it but felt it sink too much at that pace.

• EDDBUD considers the Metaspeed Sky Tokyo one of his favorites after it grew on him over time; the dual-foam setup adds stability over the Ray while retaining the softness of FF Blast Leap.

  In their words: "certainly one of my favorites in testing over the last year" · "took a little bit of time for me to get used to it" · "more stable implementation"

• A forefoot-oriented carbon-plated racer with FF Leap foam and a big landing pad up front; Kofuzi's go-to race day shoe for fast workouts and racing, though he notes it's slightly less durable than the Metaspeed Ray.

  In their words: "giant landing pad in the front" · "ideal for forefoot stompers like me" · "still a very good racing shoe"

• Both reviewers consider the Metaspeed Sky Tokyo one of the top two to three carbon plate racing shoes currently available, praising the improved FF Leap foam for delivering a lighter, bouncier, and more responsive ride than the already-excellent Sky Paris predecessor. Minor downsides include reduced stability compared to the Paris and typical ASICS outsole durability concerns.

  Ride:Dual-layer FF Leap and FF Turbo Plus midsole provides a soft, bouncy, and highly responsive ride with excellent energy return. Lighter and bouncier than the Metaspeed Sky Paris predecessor. Plate engagement is easy and provides strong propulsion off the toes. Not the most stable shoe due to the soft foam wedge at the heel, but not a major concern for most runners.

  Fit:True to size for both reviewers. Good room around the toes and forefoot, slightly more snug than ASICS training shoes like the Nimbus. Comfortable lightweight Motion Wrap upper with good heel and midfoot lockdown. Midfoot has a bit more give than typical race shoes.

  In their words: "great compact race shoe" · "really fast, really fun" · "not a particularly stable shoe"

• A propulsive, race-ready Metaspeed update — softer FF Leap bottom layer adds late-marathon comfort to the carbon-plated ride while top-tier outsole grip excels in wet cornering. Less stable than the Edge but more comfortable over the full marathon distance.

  Ride:Bigger chunk of soft FF Leap foam underneath the carbon plate gives the Sky a softer, more cushioned ride than the Edge. Less stable than the Edge — Robbie called out a heel wobble at easy paces — but once you pick the pace up it 'all comes together.' Plate position closer to the foot delivers a propulsive toe-off. Outsole grip is top-tier in wet cornering.

  Fit:Motion Wrap 3.0 upper is super light and breathable with very little structure — runs roomy in the toe box, allows toe splay, but Robbie noted some heel lift that required lacing to the top eyelet. Less constraining than the Adios Pro 4. Some give in the midfoot for runners with wider feet.

  In their words: "felt very effortless running faster paces" · "explosive feel off the toe" · "comfort with the speed"
