The ProFlex Hinged Boot System by Jackson Ultima Skates was designed primarily to address the chronic injury problems that affect today's competitive skaters. The hinge mechanism allows complete ankle mobility for flex and point while at the same time providing the necessary lateral support required for high stress moves and jump landings.

The Matrix Interchangeable Blade System allows you to exchange runners without the need to remount your skates, saving on installation costs and avoiding damage to the outsoles of your boots.

Just unscrew the stainless steel fasteners with a traditional hex key, supplied with every MATRIX chassis, remove the runner to be replaced, and fasten the new runner.
