What can you do to prevent the bruising of your toenails during the game?

Get new boots! Seriously! The feet swell up a lot in a match, about 2 years ago I bruised/broke both big toenails playing 5 a side and it took about 7 months to repir them back to normal. I had a match a few weeks ago and forgot my boots and had to wear the old pair......should be back to normal by about April 05:-(

You might also want to look at your kicking technique: the proper way is to use the side/top of your foot rather than toehacking it.
