Everything you love about IBI – ultra-comfy, vegan, knit with sustainably harvested bamboo and recycled plastics – meets the cool-classic ease of a slip-on. Slip ‘em on to wander miles, or just to grab the mail: comfort doesn't require an occasion!

Dual-Purpose, Single-Box Packaging
We’ve gone minimalist. Now our sneakers are delivered to your door in one box, which acts as both packaging and your shoe box – the box is also designed to be used for any returns as well! (All made with recycled & recyclable paper & cardboard.)

Carbon-Neutral Shipping
For our express shipping, we joined a program called DHL Go Green, in which shipment emissions are neutralized through nine diverse reforestation programs around the world. We also capture carbon through our Reforestation Program in the Brazilian rainforest.
The DNA of IBI Slip-On
