A pair can generate up to 30 pounds of CO2 emissions which is something you'd want to avoid at all cost.
The 4Steps sneakers concept by Michele Di Carlo aims to address the problem of eco-sustainability by offering a resizable pair for kids that can be used for almost five years.
The use of a 3D printer to make a pair of sneakers further lessens the environmental impact.
The adjustable 4Steps sneakers allow for customization of size, style, and color, with each part being replaceable for easy recycling and repair.
