Yes, the Feiyue trademark now belongs to Jai Alai. In 2017, Shanghai Huili Shoes Co., Ltd. officially took over Feiyue. This can be found on the website of the Trademark Office of the State Intellectual Property Office.
As for Dafu Feiyue, it belongs to Shanghai Shenglong Shoes Co., Ltd. Because China’s trademark protection law was not perfect in the early days, there were many branches of Feiyue, and Dafu was one of them. Later they also started producing and selling shoes under the Feiyue brand, which caused some confusion. But strictly speaking, Dafu Feiyue and Hui Alai Feiyue are two different brands. If you want to buy an authentic "Feiyue", you must still look for the Hui-Alai Feiyue trademark. If you are really unsure, you can also consult customer service.
