The line down the middle of RM Williams boots is called a "blocking line," which is a hallmark of the brand's unique, one-piece leather construction process. It is created when the leather is heated and clamped to form the boot's shape, and it is a sign of quality that is likely to fade over time as the leather stretches and molds to your foot.

What the line is and why it's there

  • Blocking process: R.M. Williams boots are made from a single piece of leather that is stretched and shaped using a heated machine in a process called "blocking". This is what creates the distinct, curved shape and the line down the front.
  • Sign of quality: The blocking process puts the leather under stress, so a visible line is a sign that the leather is strong and high-quality enough to withstand it. Inferior leather would not be able to hold this shape.
  • It will fade: While the line is a permanent feature of the manufacturing process, it will become less noticeable with wear as the leather softens and molds to your foot.
  • More prominent on some leathers: The line can be more visible on certain types of leather, such as oily or distressed leathers.
