ASICS Metaspeed Sky/Edge Tokyo vs ASICS Metaspeed Edge Paris

Sky felt faster and more racy at top speed over 10K; Edge felt less racy but potentially more stable and forgiving for marathon distance

Sky has plate positioned deeper in the foam, giving softer forefoot feel before plate engages; Edge has plate closer to the foot

Sky Tokyo sits the carbon plate higher in the forefoot than the Edge Tokyo.

Sky uses a flatter plate; Edge has a more curved plate closer to the Vaporfly style; EDDBUD prefers the Sky

Sky favors forefoot strikers with more foam up front; Edge flips the orientation for heel strikers with an aggressively sloped plate

Specs are identical (39.5mm heel / 34.5mm forefoot / 5mm drop / 170g) but the Sky places the new Flight Foam Leap below the plate in the heel and uses a flatter plate, giving a wilder, more trampoline-like heel and less stable ride; preferred by David for half marathon / marathon paces.

Sky Tokyo sits the carbon plate higher in the forefoot than the Edge Tokyo.

Same stack and drop but Sky has Flight Foam Leap below the plate with a flatter plate, giving a softer, bouncier heel and firmer forefoot; Edge has Flight Foam Turbo Plus below the plate and a spooned plate, giving a more structured heel and bouncier forefoot.

Tokyo models have a noticeably wider heel platform with more sole flaring than the Paris version for better rear-foot stability.

Same upper and geometry; Sky has more FF Leap (softer/bouncier) close to foot and is more propulsive, Edge is more stable but feels softer/slower for Robbie

The Sky Tokyo is designed for stride-lengthening runners with a thicker forefoot midsole and higher plate position, versus the Edge which targets high-cadence runners.

Softer, springier FF Blast layer sits at the bottom rather than the top; preference between the two comes down to personal taste

Sky is softer with a flatter plate and favors stride lengtheners/mid-forefoot strikers; Edge is slightly more resilient and durable with a more pronounced rocker for cadence-focused runners and heel strikers.

Same stack and drop, but Edge has Flight Foam Turbo Plus in the heel plus a spooned plate for a firmer, more structured heel and a bouncier, more explosive forefoot, whereas Sky puts Flight Foam Leap below a flatter plate for a softer, bouncier heel and firmer forefoot.

Edge has FF Leap directly under the foot (Sky flips the foams); Edge feels a bit more stable and both reviewers prefer the Edge in this iteration.

The Sky has Leap on top with a straight plate and is expected to feel more explosive but less stable; the Edge inverts the foam stack and uses a sculpted plate, and the Edge's Turbo Plus heel is more forgiving when tired.

Edge Tokyo has more fluidity and firmer push from the back due to FF Turbo Plus wedge; Sky Tokyo feels softer at the heel and slightly bouncier overall; plate sits lower/more scooped in the Edge so it's less noticeable underfoot.

Edge Tokyo feels closer to the previous Edge than the Sky Tokyo feels to its predecessor

The Edge Tokyo feels more stable thanks to FF Turbo Plus in the heel, though the Sky Tokyo is the more hyped pick

Edge felt less racy than the Sky at 10K top speed but potentially better suited to marathon distance due to more stable heel foam

Fraternal twin at the same 5.9 oz / 170 g weight; Sky has inverted foam orientation (dense FF Turbo Plus on top, soft FF Leap on bottom) and a wider forefoot plate for forefoot strikers, while Edge puts dense foam in the heel and soft FF Leap on top for heel strikers; Sky has red outsole rubber and a forefoot cutout, Edge has black rubber and a lateral heel cutout.

Very similar uppers and names but foam orientation and plate angle are flipped; Sky for forefoot strikers, Edge for heel strikers

Same specs (39.5mm heel / 34.5mm forefoot / 5mm drop / 170g) but the Edge uses a spooned plate with Flight Foam Leap above the plate in the forefoot, yielding a more controlled heel and snappier, more responsive forefoot; preferred for 5K/10K and courses with turns.

Plate sits lower in the forefoot and is more scooped; preference between the two comes down to personal taste

Edge has plate closer to the foot (intended for cadence runners); Sky has plate deeper in foam (intended for striders)

Edge is slightly denser in the heel, more rocker-driven, and better for heel strikers and cadence runners; Sky is softer with a flatter plate and favors stride lengtheners.

Edge Tokyo is more responsive, more stable, and more durable; Sky Tokyo is softer and may suit longer distances (half/full marathon) better, but the Edge is preferred after initial miles.
