What makes a girl's feet hot? They're beautiful, shapely, especially their arches and their toes. Painted toenails are a huge plus. So are one or more toe rings. When on display in flip flops, I just want to stare and admire a girl's feet and toes. To me, the smell of a girl's feet can be very arousing, but it depends on what she's been wearing on her feet. I've smelled girls' feet that were in flip flops all day, out of many different kinds of flip flops, like rubber ones, leather, suede, straw, and I can say about every one that their flip flop feet smelled sexy, especially when their flip flops were old and sweat-stained and well-infused with their foot scent. When a girl wears flats or heels all day, without socks or nylons, I really like how their feet smell. Nylons added to the scene can make for arousing scents also. A girl's feet smell awesome out of anything leather, a real turn-on. Now when a girl wears an old pair of chucks all day without socks, the smell her feet make in them is incredible.
I've been around other girls who slipped their shoes off and the stink was so bad I had to leave the area. I'm convinced it has to do with the brand or quality of their shoes, or else they just never wash their feet.
So to me, a girl's feet don't need to be washed to enjoy them. I prefer them sweaty and tired and dirty as long as they have an arousing type of smell. Girl's feet, their sweat glands in them, give off natural pheremones that can flip some guys' switches on. Some guys like me are triggered by this scent, while others are not.
