"these booties are sooo cute. but they are slippers, not made for outdoor use. the soles are made from a metallic fabric that is very slippery on all surfaces. these "shoes" are deadly! with that said, if you are careful, they are great for flying footwear cause they are so loose fitting. they look great with skinny jeans or leggins. they are cumbersome to walk in, very flat sole that does not flex, so you have to shuffle along. funny!!!"
