I actually have this shoe in white with aqua color, and white/pink. Love them, they're way cute. All my puma shoes I've had to break in. They all seem to be a tight-fit shoe. But you get used to them. I had a question though, for anyone who has this shoe, any color. I don't think it matters. Could they be used for running shoes? Or are they more a walking/casual wear shoe? Thanks so much! :)
