Ju Ju, have you heard of Special Feetures, a narrow shoe online retailer? I have a B fitting, which is a complete pain as the average shoe width in the UK is an E and I'm forced to buy my shoes in the US. However, occasionally this company comes up trumps! They have a website and send out a catalogue if requested. They changed ownership a few years ago and I'm not sure the offer is as good as it once was, however, they have the occasional pair that I like (they can be a bit granny like!

. I managed to buy two pairs this season with another on order.
My feet are a nightmare as they are narrow and also very shallow and I've also had Morton's neuromas surgery on both feet (ballet and also probably because I've had a lifetime of ill fitting shoes!). Sometimes I'll find a pair narrow enough but too tight for the Morton's Neuroma sites.
