My soles hit the muck with a soft slap.

The big brown hand gave the shoe a soft slap.

Xabbu's rattles and the soft slap of their feet on the sand.

But before he could answer there was a soft slap of footsteps round the colonnade.

The stone vanished with a soft slap; but at the same instant there was a swish and a bubble.

He walked back along the wooden dock and, other than the soft slap of the sea against the boats, his boots made the only sound.

It was unbearably quiet, the only sound the soft slap of their boots on the stone floor.

The doors slid open, and the sweet odor of decay hit him like a soft slap.

Then he heard the soft slap of leather on concrete, footsteps approaching.

The file landed on his desk with a soft but significant slap.
