You are so lucky to have a size 8 mens shoe size. Yep try a womens size 10 which should fit nicely depending on the style of heel. Strappy open toed heels and some pumps can be worn in one size smaller depending on the brand. Look for wide heels and maybe you can go with a size 9… idk.
With your size you can shop at any place that has womens shoes because they usually offer up to a size 11 womens in all styles. You only have to shop for style and price… lucky you! I have monster male feet… sigh.
