If you need a bit of height but want to be comfortable and supported, these feel much closer to flats as they don't pitch your food forward putting your weight on the ball of your foot.
They become like a neutral and will go with nearly everything. They are such a fun casual shoe.
The hight is not too short and not too high like some tend to be, they are awesome for regular walking and all day standing on your feet.
Womens fashion PU Leather sneakers are chic and comfortable. I wouldn't say they replace heels, especially you're going for a sexy look, but you can have fun with them. Also worn them to work even dress down.
