They are light and breathable. The bottom rubber layer is heavy and not shock absorbing at all. The fit is regular and they look pretty cute. However, I am sending them back for walking or running because of the feel and perceived quality. I feel like this puts more pressure on the arch of the foot and causes a slight misalignment of the knee. They feel rather bad underfoot and are not comfortable. I have other low-heeled shoes that are more comfortable and support proper biomechanics. It's not like this.
