Cleaning your boots in the shower: not as good an idea as it sounds
It's the easiest solution and definitely the quickest, but you really need to avoid washing your boots in the shower after a match. Not only will your coach tell you off for blocking the shower with mud, you won't be doing your boots any good at all. If you completely soak them, you run the risk of damaging the material that keeps them in shape, which means they won't support your feet as well as they should. Then there's also the fact that it will encourage mould and mildew, which can't always be seen, to grow inside your boots.
