Product Description

Unisex, timeless, and created from plant-based materials, our Suber sneaker is designed to be better for your feet and better for the planet.

Upcycled waste materials that would have otherwise been discarded or burnt are used in our shoes so they require less water, land and fertiliser to create.  Using these materials also creates extra yield for farming communities.

Cork sustainably harvested from cork oak trees is used in our footbeds, and natural rubber is tapped from the Hevea Brasiliensis tree for our soles. We use materials from trees due to their capacity to absorb carbon. 

For each pair sold we offset one tonne of carbon using gold-standard climate offsetting schemes, taking us beyond net-zero.

  • Upper; made from 68 discarded pineapple leaves, Pinatex is a durable, water-resistant material  
  • Footbed; using the natural lightweight and temperature regulation properties of cork and coconut fibres, our footbeds give long-lasting support, cushioning and breathability
  • Internal Reinforcements; made using compressed coconut fibres instead of synthetic foams and thermoplastics
  • Laces; undyed organic cotton with vegetable cellulose tips
  • Sole; 86% natural rubber, hardwearing and reducing the impact of shedding microplastics
  • Handmade in Portugal
  • Vegan
  • One tonne of carbon offset per pair sold

        how to measure your feet

        The aim is to measure the longest distance from the back of your heel to the tip of your longest toe. There are several ways, to do it, but here is our recommendation :

        step one : Put a piece of paper against the wall.

        step two :  Stand on it with your heel against the wall. Mark on the paper where your longest toe reaches to. 

        step three : Measure the distance your toe was from the edge that was against the wall.


        pinatex uppers

        The Pinatex material has a unique and very natural appearance that will develop over time and will benefit from some care.

        If dirty, your shoe can be cleaned with a damp cloth or one soaked in warm soapy water. A light rinsing can be suitable if your shoe is particularly dirty, but avoid submerging it. Always dry your shoes at room temperature to avoid damage.

        Once dried, you can apply a natural colourless wax or dubbin to protect and enhance the material. Apply a small amount to a dry, soft cloth and rub sparingly in a circular motion until fully absorbed. Do not use too much wax as it may not fully absorb. Leave your shoes to dry for 24 hours and then buff the wax with a soft cloth or brush.


        natural rubber soles

        To maintain the colour of the soles we suggest regularly cleaning them with warm soapy water.

        Our shoes are made to order to ensure as little waste as possible.  Once our pre-order window closes we place a total order with our factory. To improve efficiency with production, there may be times when we order a limited amount of extra stock which is available for order on our website.

        customs, clearance & duties fees

        As a small business we are unable to cover the cost of any customs, clearance or duties fees and so these must be paid for by the customer.



        We hope that you love your climate-considered shoes; we work very hard to ensure their fit and quality. Hopefully that means you'll have a pair of shoes that you can enjoy for a long time but if there's any reason you'd like to return your unworn footwear please firstly get in touch with us at within 14 days of receiving them.

        All returns need to reach us within 28 days. Please ensure the shoes are in their original box, unworn, and in the same immaculate condition in which they were received. Please try on your shoes on a soft surface in order to not damage the soles.



        Correctly returned items will be credited to the original payment method less any taxes, delivery or import duties incurred in delivery.



        As we make to order we can't guarantee we'll be able to make an exchange, but do always get in touch with us at and let us know what you're looking for and we'll see if we can help.


        returns postage

        As a small business we are not able to cover the cost of returns postage, and we recommend you send your shoes back on a tracked delivery service. Once we receive your return, we will inspect it to make sure the shoes haven't been worn and are in good condition, and if so we will make a refund within 3-5 days. If for any reason your return did not meet our standards, we would contact you directly via email.


        what happens to my returned shoes?

        Shoes returned to us in perfect condition will be offered to those customers who missed out in the pre-order and are on our wait list.  We aim to have zero waste.
