Hi diabolic-mind if i was you i would get some styrine plastic sheet it comes in black get the thickness you want to make a raised traction pad... I would cut little strips of it and use that clear plastic model solvent liquid i believe it melts the tracks so you can use it to fuse together the pads you make... I would put a strip across every other track or so and i bet you will get much more traction... the walkers falt is smooth tracks they don't grab to good for climbing even normal slops on dirt or anything.
