THE SHORT ANSWER
The Invincible 2, by default. Amazon's Nike ZoomX Invincible Run Flyknit stock is gone in both men's and women's sizes, so what follows is a record of what changed, not a choice you still have.
Every spec, side by side
| Spec | Invincible 1 | Invincible 2 |
|---|---|---|
| FIT AND WEIGHT | ||
| Weight | 9.8 oz | 10.3 oz |
| Official figures. Lab scales read both shoes heavier and disagree with each other by up to an ounce, so treat the half-ounce gain as the direction rather than the amount. | ||
| Widths | D | D |
| Upper | Flyknit with a heavily padded collar | Revised Flyknit with new laces and a padded collar |
| The whole update. Nike reworked the knit and the lacing to fix lockdown complaints on the original, and left everything below the foot alone. | ||
| CUSHIONING GEOMETRY | ||
| Heel stack | 39 mm | 39 mm |
| Forefoot stack | 30 mm | 30 mm |
| Drop | 9 mm | 9 mm |
| MATERIALS | ||
| Midsole | Full-length ZoomX | Full-length ZoomX |
| Unchanged, and that is the point. Doctors of Running described the 2 as mostly unchanged from the original, with some updates to the laces and upper. | ||
| VALUE | ||
| List price at launch | $180 | $180 |
| OTHER CHANGES | ||
| Fit | Narrow through the midfoot, tall padded collar | Same last, better lockdown |
| Reviewers still called the fit narrow. Wide feet were not served by either version. | ||

- Do the Nike ZoomX Invincible Run Flyknit and Invincible 2 come in the same widths?
- Yes. Both run in D for men's sizes, so a width that fit in the Invincible 1 carries over to the Invincible 2.
- How do the stack heights compare?
