The Nike Zoomx Invincible Run Flyknit 3 is a super soft, maximum cushioned running shoe with more bounce and energy yield than any other maximum cushioned shoe on the market. Version 3 has a new Strobel feed under the inner sole that gives it a firmer, more stable running feel with less energy shaft. It also has a longer heel clip to improve stability, but can cause problems for runners with wide or flat feet. It is also much harder than previous versions.
