Find clear answers about footwear development, shoe lasts, soles, prototypes, leather and material supply, production preparation and manufacturing support with Smerilli Design Manufacturing.
Smerilli Design Manufacturing supports footwear and leather goods projects from early concept through technical development and production preparation.
Depending on the project, our services may include product development, last and sole development, prototype and sample development, material selection, technical guidance, production preparation and manufacturing coordination.
We work with established brands, independent designers, entrepreneurs, start-ups, retailers, product developers, private-label clients and businesses requiring technical or manufacturing support.
Our approach is adapted to the stage, complexity and commercial requirements of each project.
Yes. You do not need to have a complete technical specification before contacting us.
We can review sketches, reference images, design presentations, physical samples or an initial product concept and help identify the development stages required to move the project forward.
Useful information may include:
You do not need to have every detail resolved. Our team can review the available information and help identify what is still required.
Yes. We can assess an existing product, authorised reference sample or prototype to better understand its construction, proportions, materials, components and development requirements.
The sample must belong to the client or be provided with the appropriate permission. SDM does not reproduce protected third-party designs without authorisation.
Yes. The shoe last determines the shape, internal volume, proportions and fit of the finished footwear.
We can help evaluate whether an existing last may provide a suitable starting point or whether adjustments or a more project-specific development route are required.
Yes. We can help assess sole design, construction, materials, proportions, tread requirements and compatibility with the selected last and upper.
Depending on the project, we may evaluate existing sole units, adapted components or a more customised sole development route.
A footwear prototype is a physical development sample used to evaluate the design, proportions, fit, materials, construction and interaction between the last, upper, sole and other components.
Its purpose is to identify potential technical issues before the product moves towards production.
Not necessarily. The first prototype should normally be treated as a development tool rather than an automatically approved final sample.
It may reveal adjustments required in the fit, proportions, patterns, materials, components, construction or finishing.
The number of prototypes and revisions depends on the complexity of the product, the quality of the original specifications, the selected materials and components, and the results of each development stage.
Some products require limited adjustments, while more complex or highly customised designs may require several development rounds.
Yes. We can review an existing prototype to help identify issues involving fit, proportions, construction, materials, component compatibility, finishing or manufacturing feasibility.
The recommended next steps will depend on the condition of the prototype and the technical information available.
A development prototype is used to test and refine the product.
An approved sample is the version that has been reviewed and accepted as the principal reference for production preparation.
Any approved changes, materials, components, colours and construction details should be clearly documented before manufacturing begins.
At present, leather samples and swatches are available for clients working with us on prototyping or production projects.
Samples may be requested to assess colour, texture, thickness, finish, handfeel and suitability before confirming a larger material order or proceeding to production.
Availability, sample size, cost and delivery arrangements depend on the selected material and the requirements of the project.
Yes. Leather selection should be based on more than colour or appearance.
We can provide practical guidance according to the type of product, construction method, required thickness, flexibility, structure, finish, performance and intended use.
No. Leather and material availability may change according to supplier stock, batch production, colour, finish, thickness and required quantity.
For this reason, availability should be confirmed before prototypes, samples or production orders are finalised.
SDM supports footwear and leather goods projects through development, production preparation and manufacturing.
The appropriate manufacturing route is assessed according to the product, construction method, materials, components, quantities and technical feasibility.
Minimum order quantities are assessed individually.
They may be influenced by the product type, construction method, materials, sole and component suppliers, custom colours, tooling, packaging requirements and manufacturing capacity.
Please provide your estimated quantities so that we can evaluate the commercial and technical requirements of the project.
Costs can only be estimated after the project has been reviewed.
They may depend on the complexity of the design, development work required, number of prototypes, materials, components, tooling, construction method, production quantities and finishing requirements.
A clear project description helps us provide more relevant guidance.
Development and production timelines vary according to the stage and complexity of the project.
Timing may be influenced by technical preparation, prototype revisions, material and component availability, supplier lead times, sample approval and manufacturing capacity.
A more accurate timeline can be discussed once the project requirements have been assessed.
Client designs, technical information and project materials are treated with care and discretion throughout the development and manufacturing process.
Where specific confidentiality terms or a formal agreement are required, these should be discussed before sensitive information is submitted.
You can submit your enquiry through the PROJECT CONTACT FORM on our website.
Please include a clear description of the product, its current development stage, expected quantities and the type of support you require.
You may also attach sketches, technical drawings, reference images or other relevant files.
Our team will review the available information and help identify the most appropriate next step.
