ASICS NovaBlast 4 Womens – 401

The Novablast 4 is ASICS’s most refined version of its signature bouncy daily trainer — updated with a more sustainable midsole, a softer and more stretchy woven upper, and an improved outsole that delivers noticeably better grip and toe-off energy than the previous generation. It’s the shoe for women who want easy miles to feel exciting and long runs to feel supported without being weighed down.

• FF BLAST™ PLUS ECO Midsole Cushioning – New bio-based foam formulation made with approximately 20% renewable content delivers cloud-like cushioning underfoot with a livelier, more energized bounce than the Novablast 3 — softer landings on easy days, responsive toe-off when the pace picks up, all from a single daily trainer
• Trampoline-Inspired Outsole Geometry – Redesigned midsole and outsole geometry creates a natural propulsive rebound effect through toe-off, giving each stride a springy, forward-driving feel that makes the shoe genuinely fun to run in across easy runs, long runs, and moderate tempo efforts
• Engineered Woven Upper – Premium one-piece woven fabric upper replaces the previous mesh construction with a softer, more elastic material that stretches with foot movement, reduces irritation, and provides superior breathability and long-run comfort with a secure but non-restrictive fit
• Tongue Wing Construction with Gusseted Fit System – Stretchy tongue wing design keeps the tongue locked in place during movement to prevent sliding and bunching at the midfoot, while the gusseted construction improves overall midfoot fit and reduces the internal friction that causes hot spots on longer runs
• AHAR-LO Outsole for Grip and Durability – Lower-density AHAR rubber outsole provides a noticeably softer feel underfoot compared to standard AHAR, with improved wet-road traction and enough durability to outlast the midsole through high training mileage
• Sustainability Built In – At least 75% of the main upper material is made from recycled content, the sockliner uses a solution dyeing process that reduces water usage by approximately 33% and carbon emissions by approximately 45% versus conventional dyeing, and reflective details add low-light visibility for early morning and evening runs
