Remember that these are just basically slippers, with sharkskin soles.
So an entire suit of sharksin armor is only -1 to move silently, with arms and legs and everything rubbing against each other. A pair of tiny slippers that just have a slightly rougher sole than normal slippers, that's a negligable penalty.
The sharkskin is an aid to the climbing, and could also be used as a way to stop the slippers from sliding around on hardwood floors. The main reason there's a bonus to move sliently is because they're Slippers.
