With lightweight fabric/leather combination boots, not much in the way of pre-wear care is needed other than the quick application of a water repellent or waterproofing agent if desired. For leatherboots, I recommend that you take your boots on a hike or two to break down the resinous materials often applied to leathers by tanneries--these resins prevent waterproofing agents from penetrating the leather. A good scrubbing with a stiff bristle brush will aid in scuffing the leather sufficiently to allow adequate penetration of sealants. Welt seams around the welt of the boot must be sealed with a welt seal to plug the holes left by the stitching process. A welt seal also serves to protect the stitching from cutting and fraying. Always apply welt seal immediately after your purchase and before applying waterproofing agents.
