I have a pair of Meermin's Linea Maestro 102461 Dark Brown Natural Calf Oxfords
in a UK 10.5. I too, have only worn them a dozen times (last time was Autumn 2012) because of size issues (I'm a 9.5 in the Capital and Duke last - Loake 1880) and the fact that they work better with a navy suit.
Whilst I have recently purchased a navy suit, (a) I have yet to have it tailored, and (b) was in two minds whether to stick with the shoes or try and eBay them. Given the difficulty in trying to sell worn shoes (albeit a dozen times), it may be an idea to explore the option of a mutually agreeable trade.
If you are a 10.5 UK, and are potentially amenable to a trade, then I'll take recent pictures of the shoes (inc. soles) to determine condition and whether we wish to pursue a trade. If so, we can then negotiate sweetening the pot a little (difference between Classic and Linea Maestro - minus condition).
Also, you're in the UK - so if near London (or thereabouts), would make a potential trade much easier. Note: ah, Cheshire. Not so near, but still workable.
