What kind of men would we be if we wore anything? Real men go commando :x
Since we're mentioning physical "abnormalities" as fails... this one has caused a bit of mocking and grief, though usually I was more proud than embarrassed by it.
Semi-Monkey feet!
I have strange feet. Family trait on my father's side, yet mine are actually "worse". I have double jointed toes. I can ball my foot up almost like a fist, I can even walk on said fist and jump and spin in the air and land back down on the knuckles of my toes. I'm the only person I know who can honestly punch-kick someone. Ball my foot up and honestly give them a jab.
There's a gap between my big toe and the rest, somewhat like a hand. My foot isn't really hand shaped, as the big toe is still protruding outward as it should, if just slightly to the side. This gap allows me to hold things very easily with my foot. I can make pasta, I can pick up objects like a pen or pencil only with my toes. I am capable of holding on to surfaces, such as if I'm in a pushing match with someone and they are trying to push me off a bed or a couch playfully I can wrap my toes around something, such as the end of a table or a part of the bed to hold on. Very strong toes.
I can do this grabbing both between the big toe and the rest of the toes, or by wrapping my toes over the object in question and squeezing between the bottom of my foot and the toes themselves.
The only real problem is buying footwear becomes slightly annoying. Many types of shoes are extremely uncomfortable. I'm more comfortable being barefoot than anything, and this has probably led to why I have increased difficulty buying sneakers, shoes, or boots. Actually if you talk about shoes in the classic sense, like dress shoes or simply work shoes, I can't wear them. They cause a burning feeling in my joints. So I wear sneakers or boots or I don't involve myself with it.
