7or9 was started in 2018 by two female friends with the goal of providing modern ladies with the most comfortable and beautiful heels possible.We focus on the research and development of comfort and technology, rather than chasing styles and trends.We apply the technology of sneakers, underwear, and even medical beauty to the design and production of high heels. Every year we release a new version of comfort.We make the classic models of heels to achieve the ultimate comfort to find the balance of comfort and beauty.
