Every spec, side by side
| Spec | Invincible 2 | Invincible 3 |
|---|---|---|
| FIT AND WEIGHT | ||
| Weight | 10.3 oz | 10.6 oz |
| Claimed figures throughout this line. RunRepeat weighed a 3 at 10.0 oz, lighter than the claim rather than heavier, which is the reverse of the usual gap. | ||
| Widths | D | D, 2E, 4E |
| Upper | Revised Flyknit with new laces and a padded collar | Thinner, denser Flyknit with a wider heel and less collar padding |
| The other half of the complaint. The 3 is wider at the heel, its laces do not run as far up the ankle, and the collar carries less padding, so testers who tried heel-lock lacing still could not stop their heel slipping. Believe in the Run titled its review "What The Heel". | ||
| CUSHIONING GEOMETRY | ||
| Heel stack | 39 mm | 40 mm |
| A millimeter at each end on Nike figures, so the drop holds at 9 mm. Both numbers are brand claims: RunRepeat measured the 3 at 35.2/25.6 mm, several millimeters under the claim at both ends, and no comparable lab figure survives for the earlier versions. | ||
| Forefoot stack | 30 mm | 31 mm |
| Drop | 9 mm | 9 mm |
| MATERIALS | ||
| Midsole | Full-length ZoomX | Full-length ZoomX over a stability layer on the strobel |
| The change that split the line. Doctors of Running measured the result as a much firmer midfoot landing and push off, and said plainly that they preferred the fit and ride of the 2. | ||
| VALUE | ||
| List price at launch | $180 | $180 |
| OTHER CHANGES | ||
| Widths | Standard only | Standard, wide and extra-wide |
| The one unambiguous improvement. The Invincible had been a narrow shoe for two versions; the 3 is the only one wide-footed runners could ever buy. | ||
