WooCommerce Storefront Images Blurry

Site is built on a child theme of Storefront.

As you can see on the page at the link, the images are blurry but when you visit the product page and open the image up, they are fine.

Images are being uploaded at 1500×1500. I’ve already tried adjusting the image sizes in the media settings and regenerating thumbnails and it didn’t work. Maybe I did it wrong though.

Any help to get the thumbnails looking good would be much appreciated.

Thanks.
