You'll just have to imagine that the main character has nice feet.
That's way overblown.
Feet as a whole pretty much disgust me.
A man should never expose his unless he's at the beach, actually on the sand or in the water (or in a shower or pool). Men should never wear sandals of any sort and flip flops are for raging homos.
Women should put theirs in the open if and only if they bother to care for them. Nothing is more of a turnoff than dirty feet with cracked polish or god forbid hair toes or something.
I do notice those that are particularly well cared for and shaped nicely, but I have no inclination to touch them or have them touch me in any way.
As a followup, I also appreciate good taste in shoes. I probably like shoes better than feet. I always notice what kind of shoes a woman has on. I also care about my own shoes.
I like to hoard shoes. I have five or six pair of underarmour shoes still in the box in my closet and at least five pair that I alternate wearing. Got a couple of Nikes I bought before Underarmour became my favorite. They're still boxed too. If I find a dress shoe I like in black, I also buy it in brown. I don't have a single pair of sandals or flip flops and I don't wear Crocs. Got a couple of pair of sanuks. Those are okay but only with certain types of outfits.
