Colo is a concept of sneakers designed to correct foot deformities and improve bad walking habits. If untreated, these problems often lead to more serious health issues later in life. The concept is therefore aimed at children between three and twelve years old, while their walking patterns are still becoming stabilized.

The design consists of shoes, a smartphone app and custom 3D printed insoles. The main feature of Colo is that its sole is designed to passively track walking habits. The function is based purely on material wear, without any use of sensors or tracking devices. A distinctive curve pattern is produced by layering on different colors of soft plastic, so specific gradients are revealed after regular use. This helps to detect the anomalies in children’s foot development, either visually or more precisely with a smartphone app. The app, after scanning the sole, tracks the progress of wear and, according to the color pattern, generates preferences for the replaceable inner sole. This can later be ordered online as a 3D printed, custom fit insole, with variable foam density that corrects the tread irregularities.

Because of its functionality, the layout of the outer sole is defined by smooth curves, whereas the top part of the shoe can offer more defined, dynamic characteristics matching current market trends. Three colored lines on each side, connecting bottom to top, also work as a visual cue for understanding the color order of the sole. Other features include easy-release velcro straps, elastic front fabric for comfortable wear, and reinforced rear part for a steady ankle position. Colo is a playful solution for children with foot health issues and also a product with a message that everybody is different and such diversity should be embraced.
