Feet are like bodies. Some are extremely slender. Some are pudgy. Some fit in somewhere in the middle. But the cool thing is that for every type of feet there are, there's a foot fetishist or admirer who loves em for being that way.
I have pudgy feet too:
....and frankly, I love them that way. I am a foot admirer, and my preference is for feet on the pudgy side. I find very few things cuter than short plump little toes. Your feet are absolutely gorgeous IMO, Ishie. Lazzy would be drooling all over the keyboard too if he saw them. And after all my years in the tk community, I can definitely tell you there are no shortage of fellas who like feet on the plump side. There are many who prefer feet on the slender side too, but fortunately there are enough feet of all kinds to go around and keep EVERYONE happy!
I hope whoever it was that apparently brought it to your attention that you have "fat feet" (which they are NOT fat...they are beautifully curvacious) did not do so with any form of menace. If they did, they are just a tactless jerk and someone you don't need to associate yourself with further. Bask instead in the admiration you'll get from the many like me who think your feet are cute as a button.
