What Shoe To Bring?

We will be leaving on our month-long vacation to Europe next week. Am I excited, heck yeah! I'm also starting to get into it. I went to Target this morning and bought medicines, band-aids, pocket tissues and other travel stuffs. I still have not decided on what kind of shoes to bring with me. I know we will be doing a lot of walking especially in Rome. I already have a comfortable black Mary Jane walking shoe by Merrell, it's very comfy and I know it won't give me any problems. I want to bring another shoe, maybe a brown sandal my Merrell also. Merrell is a well-known brand that makes comfortable shoes. The sandals are comfortable, it's soft and feels like you're walking with pillows on your feet. But it has a 11/2-inch heel, I'm a little worried that it is going to bother me after a long days walk. I hope it doesn't though since it's perfect for summer wear. I think I'll bring my leather tan loafers or brown moccasins for back-up plus a lot of band-aids and foot cream. I just hope we don't have any use for it.
