I have trouble finding shoes as well. I have several pairs of Clarks Trigenics , which are really comfortable and nice enough to wear to events , but they make less variety now.
Recently, in desperation, I bought a pair of memory foam insoled, slip on, fabric shoes from Primark... £9!! At that price I was willing to give them a try. All man made and therefore vegan. They are very comfortable, like slippers. Don't look too bad and good for around the house and short trips. My daughter thinks they look a bit cheap! They were!
