In reply to ollieollie:
If you can go to the factory shop in Richmond. You can see the boots being made through the glass wall whilst you are being measured up.
I don't have their walking boots but myself and the wife have their motorcycle boots.
I have done 20000 or so miles in mine and they still clean up like new.
In the past my boots have normally normally needed changing between 10 and 15k because they were totally work out and splitting but the Altbergs look like they will go the same distance again.
