I used them some last year. Didn't reach any shot opportunities, but I did manage to sneak up on some critters while I was wearing them. I use them to run a lot and can attest that they do allow you greater sensitivity to the ground. I plan to use them again some early in the season this fall.
A few considerations: your feet will get wet. Not a big deal if it isn't cold, but something to think about. Also, your ankles/lower legs will be relativly unprotected from briars, thorns, etc. This can be a good thing as it will encourage you to move more carefully.
