Patching Tile

[Chipper]

I have some ceramic tile in my downstairs entryway floor that have cracked. The amount of cracking is small (about 8 tiles, mostly on the edge, quarter to half-dollar size except for one of them) and the tile is light so I'd like to find a good way to "Fill" the void spots much like one would fill a tooth cavity. I don't think it's worth ripping it all out but I don't want to leave it with holes either.

The tile cracking was caused by my stupidly walking on it in my bicycle cleats and a few other things.

Can anyone suggest a good way/product to do this?

I've done the "cleat crack" myself.....only once thought, it P.O'd me sooooo bad.

About the only thing I can think of is to use the same color grout, make sure you pull out any loose pieces before you apply the grout.
