Can you please help a very fussy person find some work shoes?

[girlwithamoonandstaronherhead]

I think I've looked at every pair of shoes on t'internet.
I like very uncool, cornish pasy/clog type shoes. I like birkenstocks for example. I would prefer grey to black but would consider black if they are really nice. Dark green would also be OK.
Ballet plats a possibility if they are more rounded and less dainty!
My upper limit is about £60.
Help please!

Clarks funny dream? They are quirky and you can get them in different colours.

Thanks for the suggestions but too middle aged looking for my liking!
This is an example of what I like (but not this colour)

I've seen ones like you have linked to on Green Shoes and similar but they are way out of your price range. What about these? m.vegetarian-shoes.co.uk/womens_shoes/ally_sandal_black/11205_p.html

Can't search now, school, work etc

But look at El Naturalista, Duckfeet Shoes and Conker Shoes. Will be out of your price range unless there's a sale though, but will last forever.

I like the duckfeet, I'll look on ebay.

These? under £50 in some colours.
