- **Price:** £77.52 [^1]

- **Ideal For:** It suits overpronators seeking a road racing flat with arch support because its GuideRails system provides moderate support and helps limit excess leg rotation, while its 206 g weight and 8 mm drop support a quick, efficient stride.

### ASICS Magic Speed 4
```yaml

brand: ASICS
price_gbp: 2648.98

weight: 231 g

sole_thickness: 2.4 mm
upper_material: Engineered mesh

- **Price:** £2648.98 [^2]
- **Summary:** The ASICS Magic Speed 4 is a carbon-plated road shoe with FF BLAST PLUS and FF BLAST TURBO cushioning, a high stack, and a grippy ASICSGRIP rubber outsole. It suits runners wanting a responsive shoe for tempo sessions, fast training, and racing, though its neutral design is not built specifically for stability.
- **Ideal For:** It is not an ideal choice for overpronators seeking maximum arch support because it has a neutral platform, although its relatively firm carbon-plated ride and 42.5 mm heel stack can provide a stable-feeling base for some runners.
