Here is my initial design idea I came up with after reviewing your brief. I just kept seeing a strong, rugged foot print (or two) in the dirt, so that was the source of my inspiration. (#7 & #9 and their distressed/grunge counterparts #8 & #10)
I will continue to post other ideas as I come up with them, but feel free to comment at anytime. I think we can work back and forth on this to get it just right!
#9 #10 One note... I'm not selling or advertizing anything. This is just for personal use. No marketing. I like that it is strong. I envision two legs/feet/shoes standing from the knee down. I would love to see more!!! I do like the colors.
