Fit can vary slightly between styles, especially with different toe shapes and heel heights, so checking the product details for each pair is helpful. Many shoppers prefer their usual size, but you may wish width and whether you plan to wear hosiery or thicker socks. If you are between sizes, think about how you like your shoes to feel, more fitted for heels and more relaxed for everyday wear. Comparing measurements from a well-fitting pair you already own can also guide your choice.
