This is one shoe fad you will not be catching me in anytime this lifetime! I am sorry but these have to be the most unflattering sandals ever, which is why they were originally invented for brawny, sweaty, hairy soldiers enduring ancient battlegrounds.
This is one fashion I personally think is just plain ugly, whatever your age or size these are not going to do you any favours. Plus I bet your legs look great after a day in these exposed to the sun, that's definitely a set of tan lines it would be hard to hide!
This is when I am most happy I don't live near a fashion capital anymore and can happily ignore silly trends like this!
