Victor A970 Nitro Lite review: the all-around shoe that traded grams for cushioning
Victor replaced the A970 ACE's HyperEVA midsole with a nitrogen supercritical foam (NitroLite) and added thicker upper material. The result is more cushioned and slightly heavier than the original.
Overview
The A970 ACE, released October 2022, became Victor’s all-around flagship—widely used on international and domestic courts and popular with amateurs for looks and performance. NitroLite supercritical nitrogen-foamed midsole technology debuted on the lightweight S99 ELITE in February 2022; its eco-friendly profile and strong performance made it a headline Victor shoe technology. More than a year later, the line evolved again: A970 Nitro Lite launched on 20 November 2023, blending ACE structure with NitroLite midsole material. Lee Zii Jia wore it at the Hangzhou Asian Games in late September 2023, then took one title and one runner-up at the Arctic Open and Denmark Open— a strong international start. Two colourways shipped: Lee Zii Jia’s black/Hawaiian blue and a popular pearl white worn by Viktor Axelsen, Kenta Nishimoto, H.S. Prannoy and other top men’s singles players. The pairing of flagship chassis and new foam explains why so many pros chose it.
Appearance
The reviewed black/Hawaiian blue pair keeps the A970 ACE’s dark base but adds deep blue, indigo and Hawaiian blue across upper and midsole—cooler and clearer than the ACE’s pure dark styling. Black laser-textured PU leather remains the main upper material; iridescent sheen shifts subtly for a premium look. Side TPU film moves from single black to deep blue and indigo gradients. Gold Victor logo, brand name and “ALL AROUND” marking add luxury accents; Hawaiian blue lines highlight the cross-woven outer panel. The midsole gradient runs fresh Hawaiian blue at the forefoot to shiny purple at the heel with laser-treated metallic hints. The LS-S lateral stability TPU—iconic since the ACE—returns with laser coating; indigo surfaces still catch coloured light. The black/Hawaiian blue outsole uses purple throughout rather than a two-tone split, with Hawaiian blue wrapping the exposed carbon plate midfoot—low-key but energetic. Overall colour and pattern work is richer and more varied than the ACE’s extreme dark look, adding freshness without losing seriousness.
Technology
A970 Nitro Lite inherits ACE upper structure and core tech: V2.5 standard last, ultra-fine fibre PU with flexible lining, TPU film wrap for strength, V-Durable+ inner toe abrasion film, vent holes front and outer side plus inner and heel mesh, thick tongue and heel padding, heel collar and pull tab, and three-dimensional heel stabiliser. The LS-S lateral stability system carries over unchanged—the side TPU rising from midsole pairs with midfoot carbon plate and TPU for strong anti-torsion and midfoot lockdown. The key change is replacing ACE HYPEREVA with NitroLite supercritical nitrogen-foamed midsole (second Victor shoe application after S99), plus rear E-TPU energy pad. Nitrogen blowing agent injected into high-performance EVA yields lighter material with improved cushioning, rebound and durability versus HYPEREVA. Per shoe (EU 42): left 343.98 g, right 343.92 g—about 6 g heavier per shoe than ACE despite lighter foam, because midsole and upper materials are thicker overall. ENERGYMAX 3.0 insole ~26.70 g each, slightly heavier than ACE. Under removable insole: extra ENERGYMAX 3.0 heel layer and visible E-TPU window. Outsole: VSR rubber, round anti-slip forefoot and heel patterns, forefoot outer wrap—matching ACE detail for detail.
On-court experience
Fit and wrap: Very locked-in; for narrower feet side wrap is thick and snug without crushing. Versus ACE, overall containment is even better—especially a plusher heel—so sharp direction changes feel secure on the ankle. Breathability remains a weakness: thick upper and limited vent area lead to stuffiness over long wear, same as ACE. Cushioning: ACE already ranked among Victor’s best-cushioned all-around shoes with soft, lively feel. NitroLite pushes that further—supercritical foam polishes an already strong base. Forefoot cushioning is thicker than ACE: slightly costs launch speed but improves full-foot comfort; footing feels more solid in movement, and landing on the non-racket-side foot on rear-court jump smashes and rotations absorbs impact noticeably better. Launch: Thicker forefoot cushioning means NitroLite is not quite as fast or flexible as ACE—reduced court feel, ground contact rebound a touch sluggish. In real play the gap is modest; after long break-in it shrinks further. Players chasing extreme speed may still prefer ACE or dedicated speed shoes. Anti-torsion: Midsole carbon plus stiff side TPU and strong upper rigidity preserve ACE-level torsion control; thicker, softer upper wrap raises perceived stability further in sharp turns. Lateral support: Thick, strong upper fixes the foot well; shaped midfoot TPU extension keeps anti-roll performance very high in fast lateral work and lunge landings—ACE’s strongest trait intact. Some users still notice a slight foreign-body sensation from the lateral TPU slightly rear of midfoot; padded upper masks impact but adaptation may take time. Traction: Outsole material and pattern match ACE; grip excellent and essentially identical on court.
Overall verdict
A970 Nitro Lite inherits ACE’s soul and evolves it into a more solid, rounded, stable match shoe—main upgrade is midsole and wrap comfort. NitroLite foam strengthens cushioning while staying lighter in material terms; richer upper boosts lockdown. Ideal if you prioritise cushioning and containment over absolute startup. Relative weakness: launch speed versus ACE and pure speed models—not the pick for court-feel purists. Supercritical nitrogen foaming will likely spread across more Victor models; this shoe previews that direction.
Versus P8500 II (brief)
At similar flagship tier and price, A970 Nitro Lite suits narrower V-last feet with faster startup and plusher NitroLite/E-TPU cushioning. Victor P8500 II suits broader U 2.5E feet, heavier players and those prioritising durability and all-day stability over maximum foam softness.
How my take evolved
On paper NitroLite foam is lighter tech than ACE, but the finished shoe runs ~6 g heavier per side — thicker midsole and upper stack eat the gain. Launch vs ACE felt modest at first; after more sessions the forefoot stack made steps noticeably slower with less court feel. Many singles pros wear it; for extreme speed seekers it is a cushioned all-around flagship, not a pace shoe.
