Strange that changing it in the customizer doesn't work, because when the theme declares the image sizes that option in customizer is usually disabled. Anyway, you can easily override that in your child's functions.php file or in a custom scripts plugin with this:

PHP:

add_theme_support( 'woocommerce', array(
'thumbnail_image_width' => 200,
'gallery_thumbnail_image_width' => 100,
'single_image_width' => 400,
) );

Have you searched for that in the theme files (or maybe some plug-in), whether it is present or not? E.g. 'single_image_width'?
And if it is, what is the full code?
