Size: 40

A feather-light slip-on shoe, refined but with every-day ease and comfort.

The 100% natural crepe sole gives it a very quiet tread and a close-to-earth feel. 

This updated version uses superior construction and a beautiful and durable matte nubuck with a subtle oiled finish. 

For half sizes, add a pair of our cork insoles which are now lined with the same leather as the shoe.

MATERIALS: A subtly textured sustainably-tanned nubuck upper is breathable, durable, and biodegradable. It’s cradled by an un-dyed leather welt + thin natural crepe outsole, and lined with leather + cork insole, all of which are also biodegradable. Every component is sourced locally in Brazil where the shoes are crafted. Each pair comes with minimal recycled packaging and an organic cotton dust bag.

COLOR: Aether is deep black, mostly matte with satin notes on the texture.

Eyn Vas uses the European sizing system for shoes. We’ve fine-tuned a last that forms to the male and female foot.
