Jill, I once had a pair of Prada flats that had a big silver disk on the top, very similar to the CCs on your shoes. When I did a lot of walking, it started to really hurt, because the metal would press into the top of my foot. Leather gives, but metal doesn't bend.i have NO polish on my toes...so my pic modeling the shoes is cruddy..LOL
Let me know if your sandals are more comfortable... because I absolutely love them and wouldn't mind getting a pair.
Congratulations on your gorgeous purchases and get well soon!
