Two surfaces to inspect
The supplied before image shows marks on the white upper and a discoloured sole edge. The after image shows a different, more even-looking appearance. Compare each material separately rather than treating the whole shoe as one surface.
A coated upper and a rubber or foam midsole can need different treatment. A change in one area does not establish how another area was cleaned or repaired.
What is documented
This record consists of the image pair and the visible comparison. The exact cleaner, any coating or whitening treatment, cost and long-term outcome have not been verified. No named product is credited or recommended on the basis of these pictures.
The cause of the sole's discolouration cannot be confirmed from the photo alone. It could involve surface contamination, ageing or a previous finish.
Before working on your own pair
Check the manufacturer's material and care instructions. Clean gently and test each suitable product in a hidden area. Stop if colour transfers, the finish becomes sticky or a seam begins to open.
The white leather sneaker guide explains why cleaning, colour touch-up and midsole treatments are separate decisions. It does not prescribe an unrecorded whitening process.
Need a second opinion?
Send photos of the whole shoe and both affected surfaces, plus the make and any treatments already tried. An image of the care label is especially useful for mixed-material sneakers.
