Hello,

I have logged into your website. You are using product images that are too small then the others.

Please try to use product images of the same size to get the best results.

You can set the thumbnail size and crop ratio from Appearance >> Customize >> WooCommerce >> Product Images >>Thumbnail Width. But as your some images are much smaller so it disturbs the pixels and shows the blurry images in result. So it’s better to use the images of the same resolution for products.

Also you are using outdated theme version and plugins. So kindly update the theme and plugins to use the latest features of theme.

Best Regards.
