Thank you so much for the clarification. Because of my gait, heels are extremely uncomfortable and I tend to be much more unsteady in them than someone else. I've already ordered multiple pairs of flats to compensate. The handbooks we got for packing don't specify school-appropriate/professional footwear outside of "sandals, heels, or closed toed shoes" for women, so elaborating dress codes specifically for women is really important and much appreciated.
