I took a pair of Lacross hip boots and ground out about 4 slots (1&1/2" each) across the sole of each boot. I then cut strips of the felt for each slot and then applied as mentioned above. The thing I like about is is that I have good traction on the rocks and on the gooey mud that is often found on the trails into the "secret holes" I got tired of the all felt soles cause I always ended up on my butt hiking into them. I have had mine this way for about a year now and love it. It's like having your cake and eating it too!
