...Neither? Everyone is different. In the case of attractiveness: Some people may like skinny ankles, others may like bigger ankles. It all depends on what the individual finds attractive. Having skinny ankles may cause weak ankle bones, so a person with skinny ankles should be careful not to land to hard on their feet, and wear supportive shoes when running/playing sports. If a person has skinny ankles, they are likely to be a skinny person themselves though, so there is not too much weight to carry on their little ankles.
There's nothing wrong with skinny ankles. Some people find them a "bad" thing because their thighs are large and then their ankles are too skinny. Their a natural part of your body and no one would really care if their skinny or not. Many people who are insecure about their ankles wear anklets to attract the attention to the jewelry instead of their feet. I find it only makes people look at your feet more than not care.
If you are short & overweight- probably bad.
If you are tall & long legged, probably good.
idk, id say there is a high risk for rolling your ankle and possibly get a sprained ankle.
well,you would't want fat ankles so having skinny ones is't a bad thing!
It's a hell of a lot better than cankles. (fat ankles)
