If your page implements async/dynamic filtering and pagination you will use Javascript to include the new products in the experience.
Call the following function after the new products have been rendered:
ShoeSizeMe_loader.loadMultipleButtons()
loadMultipleButtons accepts an array of shoe ids.
If the list is provided, the script will only look for the new ids on the page, otherwise, it will scrape the entire DOM to get the new data-shoeid attributes.
