First, one thing that bears emphasis: The Invincible 3 is not an overhaul of its predecessor. Rather, it’s an all-around enhancement on the Invincible 2’s primary features.

According to the Invincible 3 footwear designers, the team was adamant about not making any radical changes to the previous style. They shared that the responsiveness, cushioning and support from the Invincible 2 is back in a sleek new look—they just upgraded the technologies that deliver it.

Of those upgrades, cushioning was primary: The Invincible 3 has more foam than both the Invincible 1 and 2, yet still manages to look less bulky. This is due to the team creating a sleeker, more streamlined design with a slimmed down silhouette as part of the shoe’s new, futuristic visual style.

“The Nike Invincible 3 is really that easy running day shoe,” said Charles Han, Senior Footwear Designer, Performance Running for Nike. “Getting people in what was essentially a racing foam, and scaling it for everyday use was super exciting. It was like uncharted territory.”

Just like the cushioning, the other improvements aren’t immediately apparent to the eye—however, they’re noticeable once you put the shoes on.

The goal is always the same with every version: To help you feel invincible when you run.
