The only shoes I will wear are Birkenstocks, even with dresses and skirts. In fact, I once went to a semi-formal dance in a beautiful yellow brocade dress with my birks!

From what I've seen of weddings these days, one can waer whatever they wish, esp. if they are comfortable!

Anyway, Birkenstock does have some nice looking sandals which might suffice. If you waterproof them, just go without stockings, as we used to do in New England, and they'll just dry out as will your feet.:-) (That store is in Connecticut, USA, but I am sure you could find some over there.)

Have fun!
