athletic sneaker 3d model

Create a fully 3D-printed orthopedic shoe intended for custom orthotic applications. The design should be seamless, with no stitching or separate parts. Include an anatomically accurate insole shape with defined heel cup, arch contour, and metatarsal support. Use a parametric lattice pattern on the upper and midsole to reduce weight while maintaining strength. The design should look suitable for additive manufacturing and biomechanical experimentation. when you make the 3D modeling the inside part should be hollow.
