I have heard this question a lot lately.
It has been written in more place than one that Mr. Hare - A black shoe company, deals only in black shoes. This has been grossly recontextualised. Mr. Hare Black shoes are black as in, of the night. Not literally. Although this is quite a good idea. Mr. Hare shoes are based primarily on the requirements of nocturnal pursuits. Should they be required for daytime action they are perfectly literate. But the night time is the right time! That is what Mr. Hare means by Black.
All of the following are Mr. Hare shoes yet none could truly be described as strictly Black.
These ones are even black and white.
Just felt the need to clear that up.
