I recently travelled through South America. Before I left I invested in some women's hiking/trail shoes: Lowa Renegade II GTX Lo.
I have to say they were the most comfortable shoes I've ever worn - supportive, lightweight, breathable and waterproof Goretex uppers - they were perfect for day hikes, walking throgh city streets, sightseeing, etc. I really recommend that you make the effort to buy some comfortable travel shoes - it will make all the difference to your trip!
Can anyone else recommend comfortable travel shoes?
