| Feature | Aerus Z | Aerus X |
| Weight / Lightness | One of Yonex’s lightest shoes. Uses special materials (e.g. Feather Bounce Foam or Feather Light X) to reduce weight while keeping comfort. | Still lightweight, but less extreme. Focused more on comfort and value over ultra-light weight. |
| Cushioning / Shock Absorption | Uses Power Cushion+ which gives enhanced shock absorption and energy return. Designed for high-impact, fast footwork. | Uses standard Power Cushion cushioning. Less “premium” absorption than Power Cushion+, but still solid. |
| Upper Design / Breathability | More advanced: seamless upper, lighter mesh materials (Durable Skin Light + Double Raschel Mesh) for better fit, breathability and lighter feel. | Shares some of upper design: may have seamless upper etc., but simpler construction and fewer premium materials. |
| Stability Features | More stability tech: Graphite plate / Power Graphite Drive to reduce twisting, plus better sole design and grip. | Less in terms of high-end stability features; more basic sole and grip. Good enough, but not at the level Z aims for. |
| Target User / Price Position | For advanced players or those who want top-tier speed, agility, and willing to pay more. | For players who want lightweight shoes, nice comfort and value. More “affordable” in the Aerus line. |
