You could do a trendier clog, there are many brands available. Also "driving slippers" are very on-trend - they have some at Madewell that are pretty comfortable, more supportive than a ballet flat. For a more casual look, there are also a TON of new slip-on sneakers which are very on-trend - search for "slip-on" sneaker on Zappos or Shopbop and you will find a ton. Vans are also an option. I am probably much more of a fashionista than you, so YMMV.
