So with any luck, here's a picture of one side. I bout a four-foot piece of 3/4-inch x 4-inch HMWPE, cut two pieces with the table saw each a foot long. To bend the ends, I clamped it into the vise, and heated it with a propane torch until it was translucent. Heat both sides, or it will crack. I recommend a fan, that stuff stinks. Once it bends, you may have to hold it there until it cools. Anyway: I then drilled three 1/4-inch holes in the shoe, and then through the plastic. On the bottom-side, I used a spade bit to countersink the bolt head so it won't wear off. Ny-Lock nuts on the bolts so I don't have to worry about re-tightening anything, and I'm all set for forever or until I wear down the shoe.
