```yaml

summary_source: generated_from_verified_specs_v1
drop: 7
weight: 8.02

```

- **Price:** £119.06 [^1]
- **Summary:** The HOKA Rocket X 3 is a carbon-fiber plated road racing shoe with dual-density PEBA foam, a winged plate, and sticky rubber for propulsion, cushioning, and traction. Its breathable single-layer warp knit mesh upper and relatively stable ride suit runners racing from 5K through the marathon, especially those wanting a more forgiving super shoe.
- **Ideal For:** It can suit flat-footed runners seeking arch support because its neutral design, Active Foot Frame, wide base, winged carbon plate, and 42mm heel provide a stable, supportive platform, although it does not provide traditional corrective arch support.

### New Balance Fresh Foam X 880v15
```yaml
product: new-balance-fresh-foam-x-880v15
brand: New Balance
price_gbp: 110.74
origin_country: null
confidence_score: null
summary_source: generated_from_verified_specs_v1
drop: 6
weight: 9.9
stack_height: 40.5 heel / 34.5 forefoot
sole_stiffness: Stiff
upper_material: Engineered mesh
```

- **Price:** £110.74 [^4]
- **Summary:** The Fresh Foam X 880v15 is a neutral road-running shoe with a high stack of Fresh Foam X cushioning, a rocker geometry, and a stable, firmer ride. It suits daily training, long easy runs, walking, and runners who want substantial protection without an especially soft or unstable feel.
- **Ideal For:** It is a reasonable option for flat-footed runners seeking arch support in a racing flat because its neutral platform, wide sizing options, high 40.5 mm heel stack, stable geometry, and removable insole accommodate orthotics, although its 9.9 oz weight makes it better suited to daily training than racing.

### New Balance Fresh Foam X 860v13
```yaml
product: new-balance-fresh-foam-x-860v13
brand: New Balance
price_gbp: 261.72

confidence_score: null
summary_source: generated_from_verified_specs_v1
drop: 10
weight: 10.9
stack_height: 27/17

upper_material: engineered mesh
```

- **Price:** £261.72 [^6]
- **Summary:** The Fresh Foam X 860v13 is a stability road-running shoe with Fresh Foam X cushioning, a dual-density midsole, and a supportive medial post. Its breathable engineered-mesh upper, durable outsole, and multiple width options suit everyday runners who want comfort and guidance for easy or long-distance runs.
- **Ideal For:** It suits flat-footed runners seeking racing flats with arch support because its medial post and structured stability design provide non-intrusive guidance, while the 27/17 mm stack and 10 mm drop offer cushioned support rather than a minimal feel.
