So I posted earlier about the numbness I was getting in my feet from the SmartTrack foot braces. So I contact cemented 5/8" blue EVA foam onto the foot brace and toe pilot, worked like a charm with no numbness.
The only negative is the they squeak if you move your foot suddenly (had on rubber soled water shoes), thinking of contact cementing on some inner tube rubber to the EVA, but is fine they way it is now.
