Tricky challenge - Boots - EEE fit for wide feet but very skinny calves.......HELP!!

[Collision]

My Mum has rheumatoid arthritis and struggles with boots as her feet are really wide but she has really skinny legs.

She is trendy but feels her shoes sometimes let her down and she is desperate for boots that dont flap!!

Any hope for her?

TIA

come on!!

Tethers - where are you?

Can't seem to find anything narrower than a standard calf fit in an EEE...
