Open-Vamp Mule Manufacturer — D6A1D

Open vamp under a single buckle strap for brand collections

Open-Vamp Mule Manufacturer — model D6A1D, developed for footwear brands, wholesalers and importers.

D6A1D leaves an open area beneath the buckle strap while retaining a rounded closed toe and open heel. That cutout changes the visual balance of a standard covered mule. Women’s collection teams can use it to introduce more exposed upper space without changing to an open-toe slide.

Develop a women’s mule around the relationship between a covered toe and a visibly open vamp.

Construction review: open vamp under a single buckle strap

Review the opening shape with the strap fastened and compare its edge to the rounded forefoot. Keep the cutout proportions fixed when assessing alternate buckle frames or strap widths.

Material specification for D6A1D

D6A1D is specified with a cow split leather upper. The material is visible around the instep opening as well as across the forefoot. Assess the edge finish, strap surface and toe panel on the same sample so the shoe reads as one design. When comparing colours, keep those construction details fixed to make the material comparison meaningful. Outsole specification: rubber. Specify the required surface treatment; a split-leather grade does not itself establish a suede finish.

Colours and variant specifications

D6A1D is listed in Apricot Beige, Grey, Purple. Choose the colour SKUs for your sample request and keep each material specification attached to its own code. Physical swatches and the approved sample establish the final colour reference.

Need EU 45, 46, 47 or another size outside the listed range? Shark Imperator supports custom size development, including new lasts and outsole moulds where required. We can adjust last shape, width, instep volume and toe allowance to your target market’s fit requirements. Send your size chart, foot measurements or reference last for assessment. Extended sizes are custom development options, not existing stock; tooling cost and development timing are quoted separately.

Private-label development for D6A1D

Shark Imperator supports OEM production and ODM design development. In a custom-design brief, show the desired vamp opening from both the top and side. Small changes to the strap position alter the visible relationship between the toe and instep, so these details should be reviewed together on a sample. Shark Imperator can support material selection and suitable brand-mark trials, along with custom labels and boxes. Keep upper decoration clear of the opening and strap edge when proposing artwork placement.

Shark Imperator works with footwear brands, wholesalers and importers on OEM, ODM and private-label projects. Send your technical drawing or marked-up reference with the changes you want to this model. Logo method and placement, hardware, material substitutions and packaging are reviewed against the selected construction before the sample specification is agreed.

Order planning and production terms

Confirm the agreed specification and schedule with your quotation. Delivery terms, freight, packaging requirements and any buyer-requested inspection or testing should be stated in the enquiry. Production timing does not include international transit.
