During some web surfing I found an excellent on-line site that is the catalog of a collection of over 2700 pairs of shoes from 155 countries and regions belonging to a museum located in Kruishoutem, Belgium.  This museum opened in 2009, after I last searched on-line, a lesson there!  It has already been a helpful resource for the Straw Sandals Project.  We were able to find

several woven shoes in our collection, that were in the Unknown category, listed as originating in the Philippines in the SONS on-line collection.  Item Ph3 above is an example of these sandals.  I have found this type of sandal on both Ebay and Etsy.  All were obtained by the sellers in the U.S. and one seller told me that they were likely brought home by soldiers and sailors returning to the U.S. from WWII, so they would have been made in the 1940’s.

I recall asking the Ebay seller from which I purchased this type of sandal if she knew about their origins.  She was uncertain of the origin but suggested the Philippines based on their design.  Our phylogenetic analysis placed them Group 4 along with espadrilles from Spain with which they share the characteristic coiled straw soles.  This link makes sense now, thinking back on the long colonial history between Spain and the Philippines.  Click here to visit the SONS on-line.
