    Luxuriously Sustainable Materials

    KOIO

    Certified Organic Cotton-Canvas

    This style’s canvas upper is woven from 100% certified organic cotton, meaning the fibers were grown and processed without toxic chemicals. High-quality organic cotton may be expensive, but it’s safe for everyone involved in the the production process (including the planet!), so we think it’s worth it.
    KOIO

    LWG-Certified Leather

    Truly luxurious materials are gentle on the environment, which is why Koios are made with leathers, suedes, and nubucks from LWG-certified tanneries in Italy. These tanneries are rigorously audited to ensure they responsibly manage waste, water and energy use, and carbon emissions.
    KOIO

    FSC®-Certified Rubber

    Durable soles shouldn’t come at the cost of the planet—that’s why 50% of the rubber used to make our custom soles is sourced from FSC®-certified forests, which are responsibly managed to prevent deforestation and land degradation.
    KOIO

    Recycled Rubber

    40% of the rubber used to make our custom soles is recycled. We gather excess rubber trimmings from neighboring factories in Italy. Why? Because these trimmings would’ve otherwise ended up in a landfill, and high-quality materials don’t belong in landfills!
    KOIO

    Non-Toxic Cotton Laces

    Our laces are woven (in Italy, of course!) from durable cotton fibers, which are lab-tested to ensure they’re free from 100+ nasty chemicals including pesticides and heavy metals.

      Cute shoe but...

      My complaint is the lack of structure to the suede. It's so loose that it looks bubbled in a lot spots. After 5 light wears they look very broken in. Mine also showed up with scratches in the toe of one of the shoes. The look like marks where someone couldnt decide where to cut the suede lol. Didnt return them because it was the third time I had to reorder them already. Not sure how long the upper part will last looking good. Had to order a size down from what I wear in Capris

      I’ve tried everything worth trying and Koios Portofino are perfect in every way!

      I tried Common Projects and returned them, I tried Oliver Cabell twice and returned them, got my first pair of Koios and this fit and look perfect! Well done! For the perfect fit size a full size down. I wear and 13 and 12 fots like a glove.

      Too narrow

      Material was good, a little thin and though compared to vans. I really wanted to like these shoes as they are beautiful however they were too narrow. I have somewhat wide feet. I made a return from a 9 to a 10 and they were still too narrow. Hopefully they will have a wide version in the future.

      Quality is great, material feels however thin compared to vans. The shoes run narrow, even when sizing up. They still feel narrow.
