Details

Sometimes the simplest designs are the most sophisticated, and the Portofino sneaker in Mineral is a testament to that. Strobel-constructed for superior flexibility, it’s handcrafted from Italian leather and unlined to give it a weightless, breathable feel. The sole is made from FSC®-certified natural and recycled rubber—so it’s sustainable and durable.

  • Handmade in Tuscany, Italy
  • Constructed from LWG-certified full-grain Italian leather (Cow)
  • Set on a 100% rubber sole (50% natural, 40% recycled, 10% conventional)
  • Tightly stitched for water resistance
  • Threaded with waxed cotton laces
  • Fitted with a removable OrthoLite® Hybrid™ insole

Size & Fit

  • Fits true to size. Take your normal US size.
  • Only available in full sizes. Go down to the nearest whole size if you wear a half size.
  • Width D - Standard
  • Unlined construction, has a soft feel and a slightly more relaxed fit than the Capri model.
  • Width can be adjusted by tightening/loosening the laces.

KOIO 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.

Compare your measurements with the size chart. If your foot measurement falls between sizes, choose the larger size.

How can we sell a $600 shoe for $245?

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 $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.
