At My Sample Factory, precision isn’t just a detail—it’s the foundation of every shoe prototype we craft.

Size differences in shoe components are nearly impossible to judge by eye alone. Even a tiny misalignment during stitching or lasting can trigger a chain of quality issues that ruin your design. When incorrectly sized sections are stitched together, the upper not only loses its aesthetic appeal but also fails to fit the last properly. An upper that’s too small puts undue tension on the material, risking tears, seam failure, or permanent contraction once the last is removed—leaving you with a shoe that looks off and fits poorly. On the flip side, an oversize upper can’t be pulled tight to the last, resulting in a misshapen, out-of-proportion silhouette that never recovers its intended form.

That’s why we enforce rigorous size marking at every stage of production. Every component is clearly labeled, every measurement verified, and every stitch aligned to your exact specifications. No guesswork, no shortcuts—just consistent, reliable quality that brings your design vision to life, exactly as you imagined.
