Comfortable women’s work shoes that go down to a size 5?

I’ve been hunting around, but everything seems to stop at a 6. My shoes that I’ve been wearing for years are literally disintegrating at this point! I’m willing to pay up to $170 or so for good quality comfortable shoes that look office appropriate. Chunky is fine if it means they’re comfortable!

I’m hoping someone knows a store that sells Hong Kong brands or something that go smaller? I bought the current ones in Adelaide from an importer from Hong Kong.

Thank you in advance!
