Customised Timberland boots

I can imagine kids getting really into this as a project for a rainy day: designing their own Timberland boots (also available in the UK).

You may not wish to divulge that the finished results can actually be ordered, given the price tag - which actually seems more reasonable in the US than over here, but still works out as an expensive activity compared with colouring in.

Timberland doesn't exactly let the imagination run wild, and I'd love to see something similar with more options for colour and pattern. Anyone know of such a thing?
