Hiking Boots. Make your hiking or walking shoes last a little longer
If the rubber tread on your boots is becoming smooth, just heat up a meat skewer till it's red hot, then lay on the sole of the boot till it burns to the required depth of tread. Repeat process until you have covered the sole. The smell is a bit strong, but well worth the effort. Comes in handy in the Winter months to stop slipping on icy ground.
