Crocs are a popular brand of casual footwear known for their distinctive clog-style design and comfortable, lightweight construction. Despite their widespread popularity, there is often confusion about what Crocs are actually made of.

Croslite: The Proprietary Material Behind Crocs

Contrary to popular belief, Crocs are not made of rubber or plastic. Instead, they are crafted from a proprietary closed-cell resin called Croslite.

This unique material is composed of ethylene-vinyl acetate (EVA), a type of polymer commonly used in various applications, including footwear, packaging, and toys.


EVA is known for its lightweight, flexible, and shock-absorbing properties, making it ideal for creating comfortable footwear like Crocs. Croslite, in particular, is formulated to provide exceptional cushioning, odor resistance, and non-marking characteristics.

Key Properties of Croslite

The unique properties of Croslite contribute significantly to the popularity and comfort of Crocs footwear:

#1. Lightweight: Croslite is remarkably lightweight, making Crocs easy to wear and ideal for extended periods of standing or walking.

#2. Flexible: The material’s flexibility allows Crocs to conform to the wearer’s foot shape, providing a personalized fit and enhanced comfort.

#3. Shock-Absorbing: Croslite absorbs shock and reduces impact forces, helping to alleviate foot fatigue and discomfort.

#4. Odor-Resistant: The closed-cell structure of Croslite inhibits bacterial growth and odor formation, keeping Crocs fresh and wearable for extended use.

#5. Non-Marking: Croslite soles are non-marking, making Crocs suitable for indoor and outdoor use without leaving scuffs or marks on surfaces.

Sustainability Considerations

While Croslite offers several desirable properties, it is important to acknowledge its environmental impact. As a derivative of ethylene, a petroleum-based product, Croslite contributes to the depletion of non-renewable resources. Additionally, the production process for Croslite involves energy-intensive steps, raising concerns about greenhouse gas emissions.

Crocs has taken steps to address these concerns by incorporating recycled materials into some of their Croslite products. They have also partnered with environmental organizations to support sustainability initiatives. However, there is still room for improvement in reducing the environmental footprint of Croslite production.


Crocs’ distinctive footwear has gained worldwide popularity due to the comfort and versatility provided by their signature Croslite material. While Croslite offers several desirable properties, it is essential to consider its environmental impact and encourage further efforts towards sustainable production practices.
