When you're camping obviously, and in the UK specifically, or even more specifically when you are going for a w/e camp in changeable weather conditions?
I have:
Walking boots
Walking shoes
Walking sandals
Flip Flops
Birkenstocks
Wellies
Trainers
I have other shoes too that are not suitable for camping.
On a more exciting note
In my profile there may be a few piccies of my FABULOUS AND GORGEOUS NEW TENT. If any of you would like to see it. It's rather special.
