I have the widest feet which makes it hard to wear certain shoes comfortably!
A easy trick i use to "break in" or "stretch out" my shoes is the plastic bag/freezer method. You can try this to your shoes to help widen the straps or even give your feet an extra 1/2"-1" in length inside the shoe.
1. Fill a zip lock bag with water, a little over 1/4 making sure theres no extra air when you seal the bag.
2. Place bag of water where you need the extra room for your feet. Usually near the toe area.
3. Place shoes inside a flat surface in your freezer.
4. Wait unitl the water completely freezes then remove the bags from your shoes. I leave my shoes in the freezer over night.
Saved me from getting rid of a few pairs of shoes becuase they fit to tight!
