Bruised toe-nail from shoes?

So I heard that you can get a bruised toenail from shoes being to small. Does this mean the nail turns black like when you smash a finger in a car door (Subhungal Hemotoma)? And how long do you have to run for this to happen? I thought this was wierd. Can this happen?Bruised toe-nail from shoes?
You bet that it can. Actually it doesn't always turn black it often just goes a darker nail colour almost a deeper pink. If you choose to wear smaller shoes then eventually the nail will come off it's bed. This will take a while. Toe nails are so resilient. They are very interesting. Also you will find that your toenails will harden up and may change to a more triangle shape on your toe. This will not look as nice as the moon shape they should be. Also lets face facts, it really hurts when you get bruised toenails because it normally affects both toes at the same time.
