Dunk, is the shadow crumpled?

Yes

It is normal that the shadow of a dunk will wrinkle when it is pressed, but it is not normal to dunk without wrinkle. In fact, no matter what shoes you wear for a long time, this will happen. If you are worried about wrinkles, either collect them, or don't be afraid to wear them boldly, or reduce the number of trips.

The original intention of NIKEDUNK is actually a pair of basketball shoes with good adhesion to the ground. (Slam Dunk is SLAMDUNK)zoomair stands for "impact air cushion", commonly known as zoom, which is often used as a buffer on Nike's top sneakers.
