R. M. Williams is an Australian footwear and clothing company. It is best known for producing chelsea boots. The company was founded by Reginald Murray "R.M." Williams and now forms part of the Louis Vuitton Moet Hennessy Group.
Williams' most successful products were handcrafted riding boots. These boots unique when they were introduced to the market, as they consisted of a single piece of leather that was stitched at the rear of the boot (the models that featured an elastic side have been particularly popular). As of 2013, the R.M. Williams Company produced handcrafted riding boots, with the use of 70 hand processes and a single piece of leather externally (with the inside lining being made up of several pieces).
