    Scraping or wearing of sole.

  • CARE

    Proper leather shoe treatment not only makes your shoes look good, but it also preserves the natural material, adding to their life. Without proper conditioning and care, leather dries out, eventually cracking and falling apart, leaving your shoes and boots an unsightly mess. Throwing a coat of shoe polish on them now again does help. But in order to maintain the supple appearance of your leather goods, you must keep them clean, conditioned, polished, and weatherproofed.

Process Driven

  • What is DIP?

    Direct Injection Process, is a process of soling shoes under highly controlled parameters. We at ACME use the most advanced German-make DESMA machines to carry out the process of injection. To know more about this you may refer to the datasheet on DIP shoes.

  • What is Pouring?

    Pouring again is a method for soling, which on the contrary is carried out in a more open and less controlled environment. Shoes produced are a level inferior than those done on DIP process.
