Although my partner has your entry
#10 and entry #8 ranked 1st and 2nd, I tend to prefer the more rugged design that he has ranked 3rd. I do like the use of the green and grey more than the blue. And in entry #8, I like how the rock life goes into the mountain (kind of like you have to go into the mountains to live the rock life), but I also like how entry
#10 has more of an overall oval.
However, I think my biggest thing is that I think it is too sleek. It makes me think more of a running shoe than more rugged outdoor sports like mountain biking, hiking, etc. Maybe if it was a little more rugged it would appeal more to me
