Botton, Botton is a factory from Guangzhou with its own brand, which mainly produces OEM cycling personal equipment. It's only been two years since I started to promote my products. There are many dealers and users in Guangdong. I don't know how it is in other parts of China. Burton's product naming and pricing are also confusing. The carbon fiber bottom entry mode is named E3, which is also a single knob and shackle design on the top. Burton also used the Atop knob, and there are different views on it in the market. Personally, I have used X-wind's lock shoes and Atop knobs. I didn't feel any problem when I used it, but a driver complained to me that the atop knob would be loose. Burton's shoes are mediocre in appearance, and the metal flannel material is added at the heel to improve the stability of the heel.
