Had a pair of Dunlop wildlife deluxe boots the ones with the lace up fronts they are made out of P. U. light as a feather and tougher than the natural rubber wellies they lasted 8 years until I walked alongside a freshly cut blackthorn hedge and a thick sharp blackthorn attached to a piece of twig went straight through the side and into my foot, I sometimes walked over 20 miles on a long day out, I must have walked a few thousand miles in these boots and plenty of that was on the road and the soles looked hardly worn, bought a second pair and they were 40 quid more than the first pair after 1
