| MATERIALS | ||
| Midsole | PWRRUN PB foam (expanded-bead PEBA) | PWRRUN PB foam (expanded-bead PEBA) |
| Same foam, softer tune, undoing the 4's firm detour. Doctors of Running's only real knock was paying $175 for a foam that did not change. | ||
| Plate | Re-engineered winged nylon plate | Nylon plate with a single medial wing |
| VALUE | ||
| List price at launch | $170 | $175 |
| OTHER CHANGES | ||
| Plate shape | Dual wings | Single medial wing |
| Cutting the lateral wing freed up torsional flex and answered the arch-intrusion complaints that had followed the plate since the 3. | ||
| Wide sizing | D only | D and 2E |
