I'm reallly struggling with my decision on what shoes to wear. I have some really great casual dress shoes (slip on's) that are super comfortable and go great with anything. I also have some running shoes that I know are great for walking but don't look very classy. Do you think that I'll get by walking the long distances with my dress shoes and still looking good or should I look like an idiot with my running shoes? Or, should I find some in between shoes?
