Dubbin is what I have always applied to leather boots- is there any alternative? It now comes in a toothpaste style tube which is really easy to apply- to everything in squirting distance as well as the boots!
One last comment- it shows how flat Dartmoor is that anyone can think of wearing wellies out on the moor. On hillsides of even moderate steepness, they are more slithery than skis.
