Anyone else wearing flip flops?

I have never been comfortable in heels for more than an hour or so. I don't understand how girls can wear heels all day everyday, totally look up to those ladies! So for my wedding (this Saturday, eek!) I plan on wearing some white flip flops. I know I'll be on my feet for most of the day and the last thing I want to worry about is hurting feet. I feel like no one is even going to see my feet since the dress goes to the floor. My FH also is only 2 inches taller than me so if I wear heels I'll be taller. My mother and my FMIL are giving me a hard time though! They think I need to wear some fancy heels or at least some fancy flats. What are your opinions? I'm hoping to get some ladies on my side! Even though I mostly see the gorgeous heels posted on here, haven't seen any flip flops yet!
