muddy boots

I bought these boots in the sale in last week of the 2005/6 rugby season when I played for Chesham Stags's 2nd XV.
I intended to keep them for the following season when I found a new team in Glasgow, but I ended up wearing them for my last game.
That was 7 and a half years ago, and I haven't played since... It appears I forgot to clean them!
they've scrubbed up well this afternoon. Now all I need to do is find a team to join to use them again!
