Best comfortable casual shoes??

I'm looking for a pair of tennis/athletic/casual shoes that are cute and low profile/not bulky so I can wear with jeans or shorts (usually I wear flip flops all summer, but will need waaay more support this time) but most importantly very comfortable to support the enormous belly I will probably have.....I'm probably supposed to gain around 60#!! (I gained 40# with my son).  
Any suggestions ladies? What did/are you wearing?
