This page has an assortment of soles that I have taken off the "Net" and I put them all together. Some day I'll catalog them and give the brand with the picture. Until then you can "right click" on the sole and it will give you some info.

These soles come in handy for law enforcement as well to make training aids. Pick a sole and duplicate it then flip it, you now have a set, make tracks etc. Also you can print 10 or so on a paper and have members sit back to back and describe one sole and see if the other person can pick which one you are describing, this will help with Radio communication skills when describing patterns in the field. Another idea UTS has suggested is to view the sheet of 10 or so for a given number of seconds or min. and turn over the sheetand have them describe a particular sole. If you have any ideas please let me know and I'll post it for others to learn from.
