This stuff is along the same lines, but you brush it on, two thick coats of this stuff will make your boots last soooo much longer!!! They sell something like it at Work zone's that works the same. Hubby and I both put this on all of our new pairs of boots, we get tons more time out of them since we started doing this. It's added waterproofing too, good for around the top edges of the soles, where they always breach on you.
