There are three primary mounting standards when it comes to inline skate boots used for all types of skating other than speed skating. It's important to know which mounting interface your boot has so that you can choose the correct Endless frame. These three mounting types are not interchangeable with one another. In other words you cannot fit a Trinity frame to a UFS boot, nor can you fit a UFS frame to a 165 raised heel boot.
