I really love the split sole all leather ballet slipper from theatricalss. These run a little bit narrow but if you have narrow feet the regular size will be great. The sizing is UK sizing so order 2 to 2.5 Sizes down from street shoe size. If it still slightly snug it's OK because the leather will stretch out a little bit over time. I use these for performance and really like the shape gave my foot and hugged my arch. The price is also really good compared to other split sole ballet slippers.
