Shielding avoids crosstalk by placing grounded or power-connected metal lines (called shields) between signal lines.

What happens exactly:
The grounded shield acts as a barrier, absorbing the electric fields from neighboring signals, which reduces the capacitive coupling between the aggressor and victim nets. Instead of the aggressor net inducing noise on the victim net, the shield absorbs or redirects that interference to ground. This prevents unwanted noise from affecting the signal integrity of the sensitive net, like the clock, ensuring cleaner, more reliable signal transmission.
