Hi ladies, I bought a pair of flats for my wedding and I decided to test them out today by wearing them at work. My left heel is starting to get a blister already so I had to put a bandage on...i'm worried that these shoes won't be comfortable enough for me to wear all day because I already got a blister. I'm wearing insoles in them becuase they are too flat to go without. if the blisters continue should i try to find a new pair of shoes?
