Unveiling the Intricacies of Modern Shoe Construction

The Art and Science Behind Footwear Engineering

At Scarpone and Sons Inc., we pride ourselves on staying at the forefront of shoe manufacturing technology. Today, we’re excited to dive into the technical details of modern shoe construction, a topic that’s close to our hearts and central to our business.

The Foundation: Lasting

One of the most crucial steps in shoe construction is lasting. This process involves shaping the upper part of the shoe around a foot-shaped mold called a last. Modern lasting techniques include:

  • Slip lasting: The upper is sewn like a slipper and pulled over the last
  • Board lasting: The upper is attached to an insole board
  • Combination lasting: A hybrid of slip and board lasting

Advanced Materials in Midsoles

The midsole is where much of the innovation in modern shoe technology occurs. Scarpone and Sons Inc. utilizes cutting-edge materials such as:

  • EVA (Ethylene-Vinyl Acetate): Lightweight and cushioning
  • Polyurethane: Durable and supportive
  • TPU (Thermoplastic Polyurethane): Flexible and resistant to abrasion

These materials are often combined in proprietary blends to achieve the perfect balance of comfort and performance.

Outsole Innovation

The outsole is where the rubber meets the road, literally. Modern outsole technology focuses on:

  • Traction patterns: Designed using computer simulations for optimal grip
  • Durability: Utilization of carbon rubber in high-wear areas
  • Flexibility: Strategic placement of grooves and flex points

3D Printing in Prototype Development

At Scarpone and Sons Inc., we’ve embraced 3D printing technology for rapid prototyping. This allows us to:

  • Iterate designs quickly
  • Test multiple concepts cost-effectively
  • Create complex geometries impossible with traditional manufacturing


The world of shoe construction is ever-evolving, and at Scarpone and Sons Inc., we’re committed to staying ahead of the curve. By combining traditional craftsmanship with cutting-edge technology, we continue to produce footwear that meets the highest standards of quality and innovation.
