How it compares
In the world of sustainable slip-ons, the IBI Slip-On stands out for its unique use of bamboo fiber rather than traditional canvas or synthetic meshes. Compared to standard polyester slip-ons, these offer superior thermoregulation and moisture-wicking properties. While recycled plastic sneakers often feel stiff, the proprietary knit construction here provides a sock-like fit that accommodates wider foot shapes more effectively than vulcanized rubber alternatives.
What to know before buying
- Verify your size using the brand's fit finder as the bamboo knit tends to stretch slightly after two weeks of wear.
- Remove the cork insoles before placing the shoes in a washing machine to preserve the adhesive.
- Air dry only; placing these in a high-heat dryer can damage the sugarcane EVA outsole.
- Consider the low-profile design which provides moderate arch support suitable for casual walking but not high-impact sports.
The IBI Slip-On is remarkably comfortable right out of the box and I love that the entire lifecycle of the shoe is carbon neutral.

Sustainability & ethics
Cariuma sources self-regenerating bamboo and utilizes recycled PET for the upper knit. The company maintains a reforestation program where two trees are planted for every pair sold, ensuring a net-positive environmental impact. Packaging consists of 100% recyclable materials and carbon-neutral shipping methods.
Pro tip
If you are between sizes, size down rather than up, as the bamboo knit upper is designed to mold to your foot shape over time.
