I went to Advance in Peterborough and they were excellent. Was duly analysed and found to be overpronating on left foot (but not right!) and somewhat embarrassed to find that the trainers I was wearing were not only rubbish but also two sizes too small

Anyway, have got a smashing new pair of Mizuna Wave Alchemy 6, if that means anything to anyone. Was pleased with the name as I understand alchemists turn lead into gold so there may even be hope for my feet!!
Thanks for all your input - much appreciated!
