How did that old advertising slogan go? We’re Number Two, we try harder? Well, poor old Peter Costello was forced into shameless media tart mode yesterday, putting his best foot forward in Melbourne at the Toorak Place Pink Ribbon Day Charity Walk.

The Treasure took to the treadmill to finish the last two hundred metres of the walk, helping to raise $5000 for research for the National Breast Cancer Foundation – and as a thank you was presented with some special PM Walking Shoes.

As a certain song about walking says “You keep saying you’ve got something for me… These boots are made for walking, and that’s just what they’ll do/And one of these days these boots are gonna walk all over you.”

But with that song – and its various versions – in mind, we think Cossie’s shaping up more and more as a Jessica Simpson, not a Nancy Sinatra.
