Have too many shoes in a shoe cabinet according to all unpleasant smells in the summer. But even in winter if you have thick shoes, but it's warm in the office all day, your feet start to sweat quickly. The shoe deodorant works for me without problems and covers all odors. How many applications it holds exactly I can not say, I hope not too few.
The smell I find not very "nice", but functional. It is to cover the shoe smell, after all. It may also be that some people may not smell this, perhaps best try in the store.
