Hi Ben,
I hope you are well today and thank you for your question.
I don’t see the blurred image on your shop page.
You can resolve the blurred image on the category page by adding the following CSS code in the Custom CSS code option of your theme on the below path.
Admin Area -> Appearance -> Theme Settings -> Custom Code -> CSS Code
body.woocommerce ul.products li.product a img {
width: auto;
margin: 0 auto;
}
Also, please regenerate thumbnails on your website using the below plugin.
