I didn't know this one yet; the website is quite sophisticated: http://www.patrick-hellmann.com/
Also, if you're interested in bespoke in Berlin, there are some addresses. For shoes, there are some small stores that carry the usual suspects like Grenson, Lobb, EG, C&J... but you can have that everywhere. For eh... unusual footwear you can have a look at Axel Bohne: http://axel-bohne.de/index.htm
Some of his shoes seem to be made by Alfred Sargent. If that's your cup of tea, you can have a look at Herr von Eden: http://www.herrvoneden.com/main.htm
PS: don't be fooled by the loud website, you can find fairly conservative stuff at Herr von Eden.
