ASICS Sonicblast — what reviewers say

Ride profile: maximal cushion , neutral stability .

  • EDDBUD found the Sonicblast surprisingly rigid with foam that feels distinct from other ASICS models using the same stated materials, suiting runners who prefer a firmer, more resilient midsole.

    Ride:Quite rigid; foam feels very different to other ASICS shoes despite claiming FF Turbo Squared; lots of stack; more resilient midsole feel than expected

    In their words: "quite rigid" · "a very different shoe"

    — EDDBUD , source
  • A tempo shoe with a plastic plate for rigidity that Kofuzi is not a huge fan of, though it serves its intended role for intense interval workouts; he notes it actually works better for heel strikers despite being in the Blast lineup.

    In their words: "not a huge fan of this plastic plate" · "switched at the hospital" · "works a lot better for heel strikers"

    — Kofuzi , source
  • A cracking lightweight, responsive shoe with stiffness and pop and a rapid-returning rocket ride; strikes a near-perfect balance of spring and energy with cushion and control, though too firm for those wanting softness.

    In their words: "stiffness and pop" · "snappy ride" · "cushioned and energetic"

    — The Run Testers , source
  • The reviewer finds the Sonicblast excels at faster paces with an impressively bouncy and snappy forefoot, but notes the heel-to-midfoot transition is somewhat rigid and jarring at easy paces, suggesting refinements could be made to the bevel and plate length.

    Ride:Very bouncy and snappy off the forefoot thanks to the Flight Foam Turbo Squared and 3/4-length Astro plate. Trampoline-like effect from midfoot forward at faster paces. Heel-to-midfoot transition can feel rigid and slappy at slower paces due to the plate and high stack. Reviewer suggests a half-length plate and larger lateral heel bevel could improve slow-pace transitions.

    Fit:Thinner, more performance-oriented upper with good breathability. Normal width through heel and midfoot, slightly wide forefoot. Semi-rigid heel counter with less padding than the Novablast 5. Good lockdown despite thinner construction.

    In their words: "likes to go fast" · "bouncy, snappy forefoot" · "trampoline effect"

Nike Zoom Fly 6 — what reviewers say

Ride profile: high cushion , neutral stability .

  • EDDBUD acknowledges the Zoom Fly 6 as a lighter, more propulsive trainer but notes that carbon plate trainers as a category are declining as brands shift to plateless designs relying on foam rigidity.

    Ride:Touch lighter than Nike daily shoes; more propulsive with a narrower footbed; carbon plate stabilizes the materials; this category of carbon plate trainers is declining as brands shift to plateless foam-first designs

    In their words: "a bit more up for it than the daily shoes" · "this type of shoe seems to be in decline now"

    — EDDBUD , source
  • #1 tempo shoe. Best Zoom Fly ever made — fun for daily training and excellent at going fast. Comfortable, peppy, lightweight.

    In their words: "comfortable. it's peppy. it's lightweight" · "everything that i want in a tempo shoe"

    — Kofuzi , source
  • Fordy says the Zoom Fly 6 is a great shoe but skews toward race-day rather than versatile training; would like Nike to make it less firm and more exciting.

    Ride:Reviewer calls it a great shoe but more towards a race-day shoe — a toned-down race-day shoe from Nike — and feels it's a bit firm; wishes Nike would inject more excitement and innovation into it

    — FORDY RUNS , source
  • An excellent versatile super-trainer that does every kind of run well; not quite as lively as the Megablast but a fantastic shoe at a much lower price, making it the value pick.

    Ride:Comfortable at easy paces yet capable of fast running; slightly firmer at the heel than the Megablast which makes it feel more stable there for some runners; not as flat-out fast or as bouncy as the Megablast but still moves well at pace

    Fit:Comfortable upper with thick dual-layer mesh, generous heel padding; true-to-size fit with secure heel and midfoot lockdown and adequate toe room

Who should buy which

Use cases the reviewers above actually call out — one bullet per distinct take, attributed. Where reviewers converge (e.g. "5K to half marathon" appearing across multiple takes) the agreement is a stronger buying signal than any single voice.

Consider the ASICS Sonicblast if

  • Heavier built runners or those wanting a stable, firm max-stack plated trainer at cruising pace — EDDBUD
  • Heavier runners who benefit from a firmer, stable super-trainer ride. — FORDY RUNS
  • Workouts, intervals (200s/400s/800s), 5K/10K, and potentially marathon racing for those wanting a smoother, faster but not overly cushioned ride — Run Moore
  • Runners who want a slightly firmer, plated uptempo trainer that can stand in as a non-carbon marathon option. — Run Moore
  • Nova Blast fans who want a snappier, plated daily trainer with some structure, or runners wanting to experiment with plates before going carbon. — Doctors of Running
  • Uptempo long runs and speed training where a bouncy, snappy forefoot feel is desired — Doctors of Running

Consider the Nike Zoom Fly 6 if

  • Versatile do-everything carbon-plate trainer for runners on a budget vs the Speed 5. — EDDBUD
  • A versatile, responsive plated daily trainer across all paces short of extreme long runs, at the cheapest price point in the group — EDDBUD
  • Marathon-block long runs and longer tempo efforts where a plush, rhythmic, road-mile-eating super-trainer is preferred — Doctors of Running
  • Workout/tempo days plus daily training in a single shoe — pairs well with a race-day Vaporfly. — Kofuzi
  • Versatile super-trainer that can handle every kind of run — easy, long, tempo, intervals — and even race day, at a much more reasonable price than rivals — The Run Testers
  • Engaging, propulsive plated tempo trainer that EDDBUD calls the best Nike shoe in a long time — EDDBUD
