I have little green wellie shoes, much the same as the above. Not only did I take them camping last year in the rain, but they went all the way round the Hay Festival and pretty much saved me from Trench Foot. I've had them for years and never thought to take them camping before the constant rain of 2012.
I've had the same pair of pink crocs from first starting camping about 8 years ago, they are now complete with Bailey's teeth marks as he likes to play with them when we camp - never shown any interest in any other shoes!
