Crocal Theme provides a built-in functionality for Breadcrumbs. You can enable them via Appearance > Theme Options > Page Options / Blog Options (Single Post Settings) / Portfolio options / Woocommerce Options (Single Product Settings) > Breadcrumbs Bar Settings respectively, depending on where you want them to appear.
