My feet have a 1/2 size difference, with the shorter one being a little wider. Shoe almost never feel super comfy on both both feet at the same time. Anyone has similar problem and how do you address this? I find adding an insole helps sometimes, some other times I have to resort to stuff cotton balls into the shorter one. Doesn't work for peep toe or sandals of course? I really don't want to buy 2 sizes for one shoe... Anyone like to share their wisdom?
