That gets him a wrinkled nose. He knows by now that the race of Men, largely, consider his feet an unusual size. For the most part, however, his interactions with them have been among Breelanders or rangers; those who had already known enough of Hobbits to glean these sorts of things. Thus, he hadn't been asked about how large his feet were, nor of the hair on them or the lack of shoes.

"Mine're as common as yours is." Bareness, fur and all. While he can keep his feet somewhat clean, he isn't willing to go through the trouble of finding shoes for himself. The thick hair on his feet tends to bend and grow sore rather easily in foot garments, and the thick soles of his feet make walking barefoot perfectly comfortable to him.
