Don't know where to start - footwear, coat

[MalcolmsBrokenWalrusMoneybox]

Hello, I've been "making do" with about 15 year old trainers and newer slip on trainers that are starting to fall apart.
Ideally I am after several "pieces" of footwear, preferably that will not need replacing too quickly, and if possible, ethical, although these tend to be out of my price range I think:
Flat or very slight heel boots
Trainers (pref dark)
Smarter slip on or ballet pumps

I'm 40 and short, either a 4.5 (clarks) or closer to a 5 elsewhere.
Please help, big TIA

Oh, I'm also after a cosy coat please.
I'm not used to spending money on myself but it needs doing, I'm sloshing about in a spare coat of my dh.
I need to look like I look after myself a bit more , I'm an embarrassment.

Oh heck, sandals or summery shoes also required.

Clarks outlet online for some bargain shoes at the moment?

I always get my coats from TK Maxx and pay between £60 and £90 for a designer one but they last years

I think Veja trainers are ethical. Check out enbrogue.com, Hannah is a complete sneakerhead and features lots of small ethical companies.

Rocket Dog do a lot of vegan shoes; not sure what their wider ethical policy is like.

Once you've found a couple of pairs to set you away, Visit several shops and get a feel for what suits and fits then keep an eye on eBay - you'd be amazed how many shoes are sold that are only tried on or new with tags

Thank you all, I am online window shopping your suggestions

I have these ballet pumps, mega mega comfy https://www.amazon.co.uk/dp/B01MXW9LWI/ref=ascdfB01MXW9LWI50758602/?tag=googshopuk-21&creative=22122&creativeASIN=B01MXW9LWI&linkCode=df0&hvadid=226940261445&hvpos=1o1&hvnetw=g&hvrand=12004659245955132201&hvpone=&hvptwo=&hvqmt=&hvdev=m&hvdvcmdl=&hvlocint=&hvlocphy=9046534&hvtargid=pla-379887337428

Oh they come in different styles too. I have those (cleo sincere) but they do cleo sass/bewitch too. Google should show you other styles, I got them off the Skechers site

Hobbs, jigsaw, John Lewis all have sales now, good luck!
