MBT, an acronym for Masai Barefoot Technology, is a type of footwear that incorporates a unique sole design meant to provide a natural, barefoot-like walking experience. Though the term "MBT" is often used interchangeably with "toning shoes," it's important to note that not all toning shoes are MBTs, and not all MBTs are meant to tone muscles. Some synonyms for MBT might include barefoot shoes, minimalist footwear, or natural movement shoes. Each of these terms highlights a different aspect of the MBT design, from its focus on the foot's natural motion to its lightweight, flexible construction.
