What are they made out of? Leather you can buy leather stretcher or use rubbing alcohol. (put on the inside and then stretch as needed. Or if they are fabric you might be able to get them wet and stretch them. I know this is probably the last thing on your mind but .... just do yourself a favor, go back to the store and get a half size bigger. So many women wear shoes that are too tight and you have no idea the horrible pain that it can cause. Imagine NEVER being able to wear heels again because of the horrible pain cuz your feet got injured from wearing shoes too small for years. If you don't believe me just google it! No reason to walk around looking and uncomfortable!
This sounds a bit weird, but both apparently work: -put wet newspapers inside of the shoes overnight -put wet socks on, then wear your shoes for a bit I had a pair of flats that were way too tight..and I ended up accidentally stepping in a puddle. Well, the water really helped in stretching them out.
Need to know how to stretch flats? well all you have to do is fill a zip lock bag 1/4 of the way with water and make sure the bag is zipped tight with little to no air in the bag as possible. Then put the bag of water inside the shoes where your toes go.( do this to both flats) . Then stick your flats, with the bags of water in them, in the freezer. Leave your flats in the freezer overnight and the next day take the freezed bag of water out of each shoe and voila.
