I hear you on the narrowness of expensive shoes! My feet are on the wide side, and I've always been able to fit in any shoe at Walmart, Target, Payless, etc. The Ferragamo shoes my MIL wears? Not so much! I've always said I have peasant feet. I am trying, however, to spend more time in shoes with some support and flexibility.
It's so frustrating to try a fabulous shoe and have it feel like walking in a stiff, tight box. Hope you find a great pair soon!
