In good representation of our cultural values, our styles will always be colorful and our approach bright and warm. Wherever you are from, if you connect with our styles, colors, story and/or mission,  welcome to the Isleñas fam :)


We use a generous memory foam in all of our insoles. Sourced from the US with antimicrobial properties, this insole provides sneaker-level comfort.


At Isleñas we don't follow the traditional fashion calendar or the latest trends. We believe in creating an identifiable style that tells a story and hope to become a staple in your own personal and unique style.


Always learning how to make our practices better for people and planet. We will keep you udated with small and big changes as we are able to apply them.

  • Small batch productions and made- to-order strategy is meant to minimize waste and only use the resources required by the demand.

  • Scraps are donated or upcycled for smaller objects like our dog collars, belts, and keychains.

  • Leathers are a secondary product to the meat industry.

  • We are constantly learning about and sourcing new material. Including leather alternative and natural fibers. Recently adding Hemp Canvas to our selection.

  • Our studio and team's skills have been a resource for testing C-Combinator's seaweed based alternative leather.

  • Our studio is VOC free. We use only water-based glues.

  • Isleñas packaging includes a dust bag only. We eliminated the shoe box (unless shipping to a major retailer).

  • Isleñas repair program aims to extend their lifespan as much as possible.

  • All orders are treated with a non-toxic water and dirt repellent so shoes are minty for longer.

  • We travel to meet our manufacturing partners in person to make sure we align in values.

Our Manufacturing

As we diversify our offering beyond espadrilles we aim to both grow our slow fashion infrastructure in Puerto Rico and continue partnering with factories in Latin America.

Currently (2024) all of our espadrilles (shoes with jute sole) and small goods are designed and made in Puerto Rico. Espadrilles are our local specialty.

All of our rubber(only) sole shoes are designed and prototyped in Puerto Rico by Karla López Rivera and made in Colombia.

We meet our factories in person, select them according to our values, and visit them once a year.

We will keep updating this information as we keep moving forward with new partnerships and products :)
