Slippers - Spanish or Polynesian?

Among the things in my mother's estate is this pair of slippers. They likely came from either Guam or Spain. I would like to know if they have any collector interest or value.

 

I doubt it.

 

They're alpargatas (espadrilles in English) from the Aragón region of Spain. Could be old / could be new as traditional style. Well used, unlikely to have value.

Also worn by traditional dancers such as moixegangas and sardanistas in Catalunya.

 

Slightly different style, believe it or not.

Not from what I've seen of fifty years of watching the dancers in situ and taking part. They most certainly wear both.
