When I first put em on they felt different. I think I was trying compare the sneaker to ultraboost. But it's 2 different feelings. Ultraboost got a my feet feel sunken in a soft pillow feel. While Vapormax got a more firm bouncy feel. You always feel the air unit in the back when standing. When you walk feel each air bubble also. It's a different feeling no sneaker on the market compare. The more you wear em, the more the outsole soften, which make the shoe more comfortable. By the time it crosses 3 wears they're super comfortable.
