Replace Shoes

ROLE
Act as a senior professional photo retoucher, fashion editor, footwear photographer and AI image-editing specialist. Perform a controlled, production-quality replacement of the shoes in the uploaded image. Treat the source image as the ground truth and preserve everything that is not explicitly requested to change.

EDIT
Replace only the subject’s existing shoes with [DESCRIBE THE NEW SHOES] or with the footwear shown in the provided reference image. Fit the replacement shoes naturally onto the subject’s feet while preserving the exact foot placement, stance, pose, leg position, body proportions, clothing and surrounding scene.

PRIMARY OBJECTIVE
Execute the requested “Replace Shoes” edit convincingly and naturally. The replacement footwear must appear genuinely worn by the subject in the original photograph—not pasted over the feet or added as a separate object. Preserve realistic scale, perspective, anatomy, lighting, material texture and ground contact.

EDITING PRIORITY

Replace only the targeted footwear.
Match the requested shoe design accurately.
Preserve the subject’s exact foot position, stance and anatomy.
Integrate the shoes with realistic lighting, shadows and ground contact.
Keep every unrelated part of the image unchanged.

REPLACEMENT SHOE SPECIFICATION

Create the new footwear according to the user’s description or supplied reference image.
Match the requested shoe type, color, material, construction, sole thickness, shape and visible details.
If a shoe reference image is provided, use it only to reproduce the footwear—not the model, pose, background or lighting from that reference.
Adapt the referenced footwear to the angle, perspective and lighting of the main image.
Preserve recognizable design details when clearly visible and supported by the reference.
Do not invent brand names, logos, text or decorative elements that were not requested or clearly present.
If a detail is unclear, use a simple and visually consistent reconstruction instead of fabricated complexity.

FIT, SCALE & ANATOMY

Fit each shoe around the subject’s existing foot position without moving or reshaping the feet.
Preserve the exact stance, stride, ankle angle, toe direction and spacing between the feet.
Maintain realistic shoe sizing relative to the subject’s body and perspective.
Preserve correct left and right shoe orientation.
Respect the natural volume of the feet inside the footwear.
Keep ankles and lower legs anatomically correct.
Prevent shoes from appearing too large, too small, stretched, flattened or disconnected from the body.
If part of a shoe is hidden by clothing, another object or the camera angle, preserve the same occlusion naturally.
Do not expose or invent toes, heels or skin that were not visible in the source.

CLOTHING INTERACTION

Preserve trousers, jeans, dresses, socks and every other clothing item exactly.
Maintain realistic overlap where trousers or fabric fall over the shoes.
Preserve existing cuffs, hems, folds and fabric tension around the ankles.
If the replacement shoes are taller or lower than the originals, adjust only the immediately touching fabric when absolutely necessary for physical realism.
Do not redesign, shorten, recolor or change the fit of the subject’s clothing.
Preserve accessories such as anklets and visible socks unless the requested footwear naturally conceals them.

PERSPECTIVE & GROUND CONTACT

Match the source image’s camera angle, lens perspective and depth.
Align the soles correctly with the ground plane.
Preserve realistic weight distribution and compression where the shoes meet the surface.
Match existing contact shadows beneath and around each foot.
Maintain correct scale differences if one foot is closer to the camera.
Preserve surface interaction with floors, pavement, grass, sand or other terrain.
Add only subtle displacement, indentation or material interaction when physically necessary.
Do not create floating shoes, incorrect sole angles or impossible foot placement.

LIGHTING & MATERIAL REALISM

Match the original light direction, intensity, softness and color temperature.
Reproduce accurate highlights and reflections for leather, suede, canvas, mesh, rubber, satin or other requested materials.
Match local ambient light, color spill and shadow behavior.
Preserve realistic surface wear and texture appropriate to the scene.
Avoid making the replacement shoes unnaturally clean, glossy or sharply detailed compared with the rest of the image.
Match the source image’s sharpness, depth of field, motion blur, grain, noise and compression characteristics.

IDENTITY & SCENE PRESERVATION

Preserve the subject’s recognizable identity, face, expression and hairstyle exactly.
Preserve body shape, pose, height, limb proportions and anatomy.
Preserve all people who are not targeted by the edit.
Preserve the original outfit apart from the shoes being replaced.
Preserve the background, flooring, architecture, furniture, vehicles and environmental details.
Preserve the original composition, crop, camera position and aspect ratio.
Do not alter the overall color grade, exposure or atmosphere.

MULTIPLE PEOPLE & TARGETING

Replace footwear only on the clearly targeted subject.
If multiple people are visible and no target is specified, replace only the shoes belonging to the main subject.
Preserve every other person’s footwear exactly.
Replace both shoes as a matching pair unless the user explicitly requests a single-shoe replacement.
Ensure both replacement shoes share the same design, material and condition while respecting their different viewing angles.

STRICT PRESERVATION RULES

Do not change anything outside the requested shoe replacement.
Do not modify the subject’s legs, feet, body, face or pose.
Do not alter clothing except for tiny local adjustments required where it physically overlaps the new shoes.
Preserve jewelry, tattoos, scars, accessories and distinguishing details.
Preserve all readable text and logos outside the targeted footwear.
Do not introduce props, decorations, people or environmental changes.
Do not crop, reframe or extend the image.

ARTIFACT PREVENTION
Avoid:

oversized or undersized shoes
incorrect left and right footwear
floating feet or missing ground contact
mismatched shoe designs
distorted ankles or lower legs
changed stance or foot direction
impossible sole angles
shoes intersecting the floor or clothing
missing or duplicated laces
malformed heels, soles or toe boxes
invented logos or corrupted text
inconsistent lighting or shadows
plastic or painted material texture
pasted-on appearance
changes to the subject’s outfit or identity
modifications to other people’s footwear
obvious generative-AI artifacts

QUALITY CONTROL
Before finalizing, compare the result carefully with the source and verify that:

only the targeted shoes have been replaced;
the requested footwear design is represented accurately;
both shoes form a consistent and correctly oriented pair;
foot placement, stance, anatomy and body proportions remain unchanged;
shoe scale and perspective match the original scene;
trousers, socks and nearby clothing overlap the footwear naturally;
soles make convincing contact with the ground;
lighting, shadows, reflections, texture and sharpness are coherent;
no unsupported logos, text or design details were introduced;
every unrelated element remains faithful to the source;
the final result remains believable at close inspection.

OUTPUT
Return one polished final image only. Preserve the original aspect ratio, resolution and framing. Use the highest practical image quality and detail available. Do not add captions, watermarks, borders, comparison labels or explanatory text.
