AUXETIC INSOLE LABSTEP-BY-STEP PARAMETRIC DESIGN

01 / SHOE SIZING LAST

Choose your shoe size first. The outline scales from this size, then you can tune its shape.

Estimated foot length260 mm
Derived insole length270 mm
Shoe-size conversion is a starter estimate, not a universal brand standard. Shoe lasts vary. Measure the foot or check the actual shoe before manufacturing.

First validate the footwear size and outer silhouette. We will add the next stage after you review this one.
