Where can I find a flat, black leather chelsea boot?

[NigellasGuest]

The closest I've come to is in Office but it's black rubber

I really need to get ankle boots that are flat, preferably a Chelsea boot.
Has anyone seen any?

Asos?

Amazon? www.amazon.co.uk/dp/B001387QCI/?tag=hydra0b-21&hvadid=9550951629&ref=asc_df_B001387QCI

Topshop

I have the asos ones

Have managed to look at both of the links above but not the amazon one (am on my phone) - they are both very hopeful!

I've realised I'd like a squarer toe

Are there any out there?
And are they pretty much waterproof?
