3D scan data of a customer or patient’s feet is acquired and used to create uniquely contoured soles that allow for proper ergonomic support and promote a natural gait. The footwear is customized to the scan to create unique designs that use inputs from podiatrists and foot care professionals.
Simpleware lattice tools are employed to create lattice structures from original CAD files and ‘boolean’ a variety of solid surfaces to the lattice structure. Lattices are created from solid STL files easily and accurately to create and modify certain areas of the lattice based on unique foot and gait characteristics. Simpleware morphological 3D editing tools are used to adjust areas such as the heel and arch areas.
Footprint’s original midsole and insole designs are laser sintered (SLS) out of an advanced TPU powder and coated with a polyurethane finish for durability and waterproofing. Manufacturing is carried out following virtual testing of designs, reducing the waste associated with traditional mold-making processes. Footprint often repurpose the soles from existing shoes to test out new designs.
