Proper leather shoes

The inner sole has worn out and curled up in one of my boots. So I'm after a new cheap leather innersoles.

Anyone know if they're all much of a muchness?

I was looking at these odour resistant ones : http://www.ggfootcare.co.uk/store/content_prod/14/2

or

these plain leather ones: http://www.ggfootcare.co.uk/store/content_prod/14/2078

Cheers.

Just go to a place that sells hides and buy a big enough piece to cut two inners out of. With your preferred thickness, get a perfect fit by tracing around each foot and cut out with a sharp knife. Lasts way longer than those micro thin things that shoe stores sell.
