The Portofino in Shadow is Koio’s elevated take on the classic plimsoll—minimalist, monochrome, and made for everyday wear. Handcrafted in Italy from black full-grain calf leather, it features a light, breathable construction lined only at the ankle. The tonal rubber sole is Strobel-constructed for optimum flexibility and long-lasting comfort. Style it with black chinos and a charcoal knit polo, or dress it down with dark denim and a crisp white tee.

How To Measure Your Foot
Follow these simple steps to find your perfect size. You'll need a ruler and a sheet of paper.
1. Place the sheet of paper against a wall or straight edge.
2. Position one foot along the sheet of paper, pressed against the wall.
3. Align a ruler beside your foot.
4. Measure the length in centimeters or inches from the tip of your longest toe.
5. Repeat the process for your other foot.
The measurements reflect the maximum length foot that fits into each size. Therefore, you want your foot measurement to be slightly shorter than or equal to the size you choose, depending on how much room you like to have in your shoes.

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 $600 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.
