Introducing the Mello, a first-of-its-kind luxury sneaker that restores the planet—and biodegrades back into it. Handcrafted in Italy with vegetable-tanned regenerative leather from the Swiss Alps, this Castagna colorway is set on a lightweight and durable LACTAE HEVEA® sole that's handmade from responsibly sourced hevea-tree milk. The recycled corn, wool, and kenaf insole delivers cushioned comfort all day long.
The outsoles may differ in shades of 'cream' due to the different levels of carotene in hevea milk tree which is the natural property of a biodegradable sole.

How can we sell a $800 shoe for $395?
We cut out the middlemen.
Our Value At Koio we’re striving to make the most valuable shoe on the market. For us, value doesn’t come from an outrageous ticket price; it comes from pairing ethics with the highest-quality Italian materials and craftsmanship to create the best shoe we can, and pricing it at a fair margin that allows us to do business sustainably.
Our Quality Each of our shoes passes through the hands of 42 craftspeople at our manufacturer in Italy, using locally sourced premium leathers, suedes, and recycled materials. We’re creating footwear that’s matched only by the world’s most renown luxury brands in its dedication to quality. How do we know? Because we see their shoes being manufactured next to ours by the same craftspeople.
Don’t get us started on retailers. Italian leather shoes of comparable craftsmanship are sold for twice the price of Koios or more. When a luxury brand sells a shoe to a retailer, the retailer applies a markup of at least 100% to the wholesale price—the price that they are paying the luxury brand—in order to come up with the price that you are seeing in the store. When you buy a pair of $800 leather shoes through retail, at least half your money goes to the store location.
We get around the unnecessarily pricey world of traditional retail by selling the finest Italian leather shoes directly to you. Here's to getting the best value for your money.
