Hello and greetings! I have here these M&S/Marks And Spencer 'Oxford' style formal/dress/occasion shoes, complete with a genuine leather 'upper' and fantastic condition - I have worn them so scarcely they still smell new! They are a UK Size 10/EU 44. The only issue is, I was trying to clean the outsole/tread part, and some water must have gotten onto the 'upper' and now on the left shoe there is some localised, almost imperceptible discolouration, while the right shoe has gained this uneven texture in certain areas, such as the 'tongue' area. Not sure what happened there. Perhaps someone with more tenacity than me may be able to sort them out? Any questions, do not hesitate to ask.
