A. Explore the app's settings to see if there is an option to add or select more stores. Some apps allow users to customize their store preferences. Go to 'Settings' > 'Store Preferences' and check if you can add more stores.

B. If the app is limited in store options, consider using other sneaker apps or websites that may have a broader selection. You can also check social media platforms or sneaker forums for recommendations on where to find specific models.
