I recently purchased these ballet slippers as replacement for my old Bloch Zenith slippers and I am very happy with the switch. I loved the Zenith for the way it fit my foot, but I never liked the ugly salmon pink colour that they come in. I also never found them particularly comfortable. The Performa comes in a beautiful light pink colour (hopefully Bloch will start making more styles or shoes in this colour) and I can now easily match them to tights. They have a nice large foot pad which I find makes them a lot more comfortable and easier to balance in. They also come lined, which the Zenith doesn't. They have a great fit and I am so happy to have made the switch to these shoes :)
