I have also gone from problem like this.I have set up taxonomy path for my site where the
i have used default taxonomy views.
In your case i guess "Product" is your content type& you entered data using taxonomy & you want those vocabulary display here with term you referenced.
I am suggesting to use drupal module "Custom Breadcrumbs". You can set path using this modules views portion.
If you have view for menu (here i guess 'shopname').Select your views path.Place your referenced field in title & path using token given there & save.
In configuration settings check first & third option to place hierarchy of taxonomy in your path.& other settings for taxonomy as your need.
Hope this could work..
Thanks
