Phenomenal Shoes
The Koio Portofinos are stunning shoes that are exceptionally comfortable, with a build quality that is second to none. I have always preferred the clean aesthetic of a flat, low-profile sole, but most brands fail to deliver the necessary support, making them impossible to wear for long stretches. Koio has completely mastered this balance.
Despite the sleek, low profile, the sole is incredibly supportive. These are easily all-day shoes that effortlessly transition from a sharp office environment to a night out on the town. They have officially set a very high bar for the competition.

Solid
Was looking for a solid basic white and this fit the bill. Usually wear a US 9.5 but got a size 9 and they fit great.
