READ Timberland Premium 6" 8658A Black Waterproof Hiking Boot Women’s Size 6.5 M

There is sticky, shiny residue on the bottoms and midsole of the left boot. I am not sure exactly what this is or where it is from. Great used condition otherwise. These shoes have been lightly worn and show only minor signs of wear as pictured. 7.5/10 condition Item number: S51-0
