The ability to pull your toes/front of the foot towards your shin is called dorsiflexion.
You may not realize how important dorsiflexion is, until you lose it.
The lack of dorsiflexion can cause a person to walk with the feet/toes pointed out.￼
A loss of dorsiflexion can cause the heels to rise when attempting to do a squat. On that note, there is a difference between a squat and a crouch.￼
There are ways to improve this.
