Espadrille advice?

I am in the market for some flats, and I was thinking espadrilles might just be perfect, since I have ridiculously sensitive feet and always get heel blisters from stiff canvas shoes. Does anyone have recommendations for a really comfy flat or espadrille? Something cute to wear with dresses?
