Eco Friendly Footwear Materials: Crepe Rubber!
Aug16
Crepe soles, or crepe rubber soles are widely used in footwear and in boot manufacture. Because of the durability and relatively low cost, crepe rubber has been used for decades, but what isn’t known is how eco-friendly crepe rubber can actually be.
Depending on the process, natural latex and rubbers have a rough hewn textured look although crepe rubbers can vary somewhat in texture and in color. The material is produced through a process called coagulation which combines melted latex with a natural coagulum – shell scrap, bamboo, jute fibers and even tree lace are often used in combination with the latex and the crepe rubber is the product.
The process is fairly inexpensive and the materials used can be entirely natural, making crepe rubber a smart option for casual shoes. It’s hard for organic and sustainable footwear companies to keep costs low, so crepe rubber can be a terrific option.
The color variance in crepe rubber is dependent on the amount of natural dirt or other contaminants allowed to remain in the material. Basically, higher grades of crepe leather have dirt and other contaminants removed during extra steps during production – which therefore adds cost to the material.
Crepe rubber is a great choice for eco-friendly casual shoes. The texture and color can be taken into consideration and actually add to and work with the style of the shoe. The rubber sole can reduce impact on your feet, ankles and knees and, when used properly, crepe rubber soles add traction to minimize slippage in wet situations.
So which of our eco-friendly brands use crepe rubber in their production? Well, a number of our shoe makers use rubbers melded with eco-friendly materials, but only a few specifically cite crepe rubber in their materials.
Groundhog Shoes – Groundhog shoes use crepe rubber made from the Lactae Meva Rubber tree.
The natural liquid latex is actually tapped from the trees and collected and the trees and process are both sustainable practices.
Groundhog uses crepe rubber soles in many of their shoes to offer support, comfort and sustainable materials.
The North Face Shoes – The North Face uses crepe rubber as a mudguard and heel reinforcement for added eco-friendly heel support and extra protection in wet and muddy conditions.
The North Face is working hard to integrate sustainable materials in creative ways into all their rugged shoes and this innovative use of crepe rubber as a support material and trim is a testament to their smart and sustainable design!





One of the most egregious wastes in the shoe industry has been packaging. Between the paper used to stuff the shoes so they look their best to customers, to the paper used to wrap the shoes before they are enclosed in fancy shoe boxes, the sheer amount of paper and pulp used is a little ridiculous.
When I think about
Ultimately, a process was developed where bamboo fiber could actually be derived from bamboo pulp. This fiber has been made into all kinds of fabrics that contain several natural benefits that come from the Bamboo plant. Bamboo fabric is soft, UV resistant, anti bacterial, soft, absorbent, and can even aid in temperature regulation.
The soles of the shoes are made up of several layers or environmentally friendly materials. First, the bottom is constructed of molded natural rubber. This Crepe rubber is actually harvested from the sap of sustainable rubber trees and made into a latex compound to offer good gripping tread and water protection. The footbed itself is made of a coconut matting, entirely biodegradable and offering a firm but comfortable cushion for walking and support. Finally, the footbed on the interior of the shoe is a soft fabric made with bamboo charcoal – also biodegradable and offering one of nature’s most effective anti bacterial and anti odorants! This bamboo charcoal fabric also has excellent insulating attributes making Groundhog boots and shoes a great choice for fall and winter!
Additionally, Groundhog ships by sea carriage, one of the more eco-friendly shipping options, to reduce the carbon footprint of their shoes. As shipping makes up about 2% of the greenhouse gas emissions worldwide, this practice is quite important. Groundhog shoes also works hard at finding materials for their shoes locally, to reduce more shipping costs and unnecessary emissions – as well as to support local economy, a human friendly practice!
