A few months ago, Pict posted about keeping a magnetized razor blade under the insole of his shoe ( here ). Today, I suddenly had an idea about putting other survival kit in your shoes. I tryed it out by putting: a razor blade, 2 needles, some strong thread, a 20p piece for a phone, and a thin plastic mirror. It worked, I couldn't feel it at all. I had some other ideas for things that you could put in there; a fishing kit, safety pins, survival cheat sheets, duct tape, plasters, wire, foil and maybe ever paper matches.

Any ides, thoughts, suggestions?
