Just a quick update.
I ended up going for two pairs:
Spiked - Under Armour HOVR
Spikeless - Footjoy Pro SL
Both were 11 (half a size up from my usual size) and both in a wide (E) fitting.
It's remarkable how much more comfortable they are - I can play three times in a week with no trouble at all (well, foot-wise, anyway) whereas previously I would have been hobbling about for a day or so.
Many thanks for all the suggestions!
