Sorry, I was talking about 'normal' leather which I would imagine 99% of people here will have their shoes made of - I wasn't even aware of shoes made from yak leather? - I have had Ecco shoes before though so I will check out their yak range ... Paul
i honestly dont see how the yak leather on my ecco bioms will ever crack. they are as soft and maleable today as they were when i first got them nearly 2 years ago.
