Search for shoes

Now I really am beginning to feel old! At the moment when I go out for my walk or even into the centre to do shopping, I wear a pair of sandy nubuck ankle boots that resemble those worn by builders, but I got mine for just a few pounds some years ago in Lidl. They are extremely comfortable and because I have back problems they are perfect for walking any distance.
As these boots have a nice faux sheepskin lining, I really don't think they will be suitable to wear when the weather gets warmer and I am certain that they will not look right with lightweight summer clothes or cropped trousers!
What I would like to find are some shoes that look reasonably elegant with a wide separate heel about an inch or so high with adequate support around the back of the heel and not costing the earth. All I can find are flimsy fashion shoes with a one piece sole and heel moulded from some cheap looking plastic with no support around the back of the heel, poorly made and costing the earth!
I always used to buy shoes at Marks & Spencer as they were well made with good materials and were reasonably priced, but I haven't done so for several years because they no longer seem to want the custom of the more mature lady with conservative taste. All their shoes are for the young and fashion conscious with heels that would cause me to fall and break my neck and I would need to take out a small mortgage to pay for them.
The cheaper shoe shops seem to be selling off their winter stock because one has an offer of 'buy one, get one free'. I'm not sure if they mean buy one shoe and get the other free or maybe they're really desperate to get rid of all those Ughh! boots!
Perhaps I will have to wait a bit longer to buy shoes and hopefully I won't end up going barefoot!
