I haven't really gone walking barefoot in the bush since I became an adult, but I do like my huaraches style sandals similar to these: http://www.instructables.com/id/Minimalist-Running-Sandals-Huaraches/ . I went shares in a sheet of flexible shoe rubber with someone. They stay on the foot much better than thongs and I find that I walk pretty much like when I am barefoot. Thongs tend to change how you walk to keep them on. I also make good use of one of the more affordable minimalist shoes - the good old 'tennis shoe'. Flat, flexible and easy to find at anything upwards from $5 a pair. Because bought shoes invariably come with a narrower toe box than what I personally find comfortable, I buy them big and wear thick wool socks to prevent floppy shoe rub.
