Boot Lasts:Selecting lasts for boots of varying heights (ankle, calf, knee-high), considering leg and ankle fit, shaft shape, and structural support.
Sneaker Lasts:Choosing lasts for athletic or fashion sneakers, considering toe box volume, heel counter shape, and overall sporty or casual silhouette.
Last Material and Construction:Specifying the material for the shoe last, typically wood, resin, or high-quality plastic, chosen for durability, stability, and ability to hold precise shapes.
Custom Last Modification or Creation (Bespoke Luxury):For high-end luxury designers seeking unique shapes or specific fit requirements, considering custom last modification or even bespoke last creation. This allows for complete design freedom and a truly personalized shoe form.
Last Preparation for Pattern Making:Preparing the selected shoe last for pattern engineering, ensuring its surface is smooth and marked with key reference points to guide accurate pattern creation.
4.Pattern Engineering – Translating 3D Last to 2D Shoe Components :
With the shoe last chosen, skilled pattern makers translate its form into 2D patterns:
Last-Based Pattern Drafting:Creating patterns for each shoe component (upper pieces, lining, insole, outsole, reinforcements) directly from the shoe last. This ensures that the patterns accurately reflect the 3D shape of the last and will wrap correctly around it during assembly.
Style-Specific Pattern Adjustments:Modifying patterns based on the specific shoe style and design details. For example, patterns for pumps will be engineered differently than patterns for boots to accommodate their unique constructions.
Material Allowance and Seam Integration:Incorporating allowances for material thickness, stretch, and seam overlaps into the patterns. This ensures that the assembled prototype will fit correctly on the shoe last and have clean, well-executed seams.
Pattern Digitization (Optional):Digitizing the finalized patterns using CAD software for precise cutting and storage. Digital patterns can also be easily modified for size grading in later production stages.
5.Material Sourcing and Preparation – Selecting and Preparing Luxury Components:
