+2.2 Energy Return & Bounce+2.2 Underfoot Rebound: Snappier propulsion and mechanical return through toe-off.


+2.2 Underfoot Rebound: Snappier propulsion and mechanical return through toe-off.
+2.1 Traction & Grip: Higher-traction compound for wet roads and fast corners.
Side-by-side selection criteria grounded in verified mechanical specs

Choose the Novablast 4 if your priority is explosive energy return and dynamic toe-off propulsion powered by FF BLAST+ Eco supercritical foam and a noticeably lighter weight (260g vs 292g). It is the better match for runners targeting race-pace velocity and responsive tempo efforts over the Speedgoat 5's focus on neutral support and surefooted stride containment.

Choose the Speedgoat 5 if your priority is tenacious rubber bite across slick pavement and wet turns powered by Compression-molded EVA (reworked slab) (292g). It is the better match for runners targeting all-weather grip and confident cornering on slick streets over the Novablast 4's focus on high-mileage protection and low-impact recovery cruising.
Critical biomechanical trade-offs to avoid buying the wrong shoe
Skip Novablast 4 if you need medial guidance for moderate to severe overpronation; the tall, softly sculpted platform shifts under lateral load.
Skip Speedgoat 5 if your mileage includes paved asphalt or concrete; aggressive 5mm lugs wear rapidly on hard surfaces and cause harsh ground shock.

Cohort-relative percentiles and verified technical specs
›ASICS Novablast 4 saves 32g per stride, noticeable after mile 6 of continuous running.
›ASICS Novablast 4 delivers 8.5mm more vibration isolation for long recovery efforts than Speedgoat 5.
›Novablast 4's 8mm drop shifts load toward the knees/quads, while Speedgoat 5's 4mm drop engages the Achilles and calves.
›FF BLAST+ Eco supercritical foam yields a springier, high-rebound toe-off compared to Compression-molded EVA (reworked slab)'s grounded, stable feel.
›Speedgoat 5 utilizes Vibram Megagrip with 5mm Traction Lugs compound formulated for extended 500+ mile abrasive asphalt longevity.
