Jacksback: yes, I like those. I haven't been into Clarks this season (local one has closed down, which means braving the huge shopping centre which I struggle with) but should do so. They may still be a bit harsh on the poor bunions, and depends if they have removeable insoles (so that I can add my orthotics). As someone suggested upthread, I should try shoe trees - see if I can stretch the buggers to fit round my hideously deformed trotters.
Fitflops - i have the orignal fitflops (don't go out in them, but for summer in the house/garden). Must go and have a look at their full range.
There are more possibilities to explore (thanks for the PPs who have recommended brands) - I just need to find time, patience, and the right frame of mind. Trying on shoes when you have issues like this is so demoralising.
PaulHollywoods: yes, definitely like the brogue look if I can get some comfortable enough. Probably not with trousers (a bit too short and dumpy, and my relatively small waist compared to hips means they rarely fit well) but with opaque tights and a dress maybe. My legs aren't toooo bad from the knee down.
I haven't looked at fashion mags for about 25 years (!) and don't look at stuff online but I do look at people I see out and about when I go out (which admittedly is not often). There's a woman who does a hobby that I do and she is taller than me but probably chunkier yet she looks amazing. She wears shirt-waisted dresses (beautiful fabrics, mainly strong single colours), with opaque tights and ankle boots. Never seen her in the same thing twice so she must have a huge wardrobe. Good hair and make up. I should pluck up the courage to tell her I love her style. I guess she has just worked out what suits her and she sticks with it.
btw, nothing wrong with M&S - I still think it's really good quality for the price and it's a safe go-to for essentials (underwear, although I know their bras aren't the best, t shirts etc) but I just feel like I've turned into my Mum. There's a Victoria Wood sketch, isn't there, where she sees - I think - a pair of scholls and says 'mmm, they look comfy'. That always comes to mind when I'm in M&S.
If I had more money I would love to shop in Jigsaw, Boden, Fat Face, Joules but it's a bit beyond me. I know, though, that in theory it's worth pushing the boat out for a few nice pieces.
