This may extend all the way around the boot, but should at least protect the most critical areas near the toe and heel of your boot. If your boot does not have a rand, or if it does not go all the way around, you will have to pay special attention to the seal between the upper and the sole when you are applying waterproofing materials. The boot we show here is made of leather. Other boots are made of a combination of leather and tough water-resistant fabrics. With the right construction and well waterproofed leather, a boot will not really need a liner to keep water out.
Liners are another compromise.
If you will be hiking in very wet areas, they will help keep water out, but this happens at the expense of making your boots hotter to wear. If your feet have a tendency to sweat, then they will become wet as a result of the increased heat. Think hard about how much you really need your boots to include built-in liners. A combination of the two help you quickly and easily adjust and fine-tune the way your boots fit on any given day. The gusset is the flexible leather part that attaches the boot's tongue to its body.
