The USD Basic Dual Fit Liner is a universal liner for aggressive skates, which can be found in the basic models of Aeon, the flagship products of the USD brand. Designed to provide maximum comfort and support, the USD Basic Dual Fit liner is a combination of high-quality materials that provide a balance between stiffness and flexibility. The liner with increased volume will perfectly fill wider shells, and a convenient carrying handle will make them easy to transport.

The USD Basic Dual Fit liners also have moisture-wicking fabric to keep feet dry during intense activities. The liners offer a dual size range and, thanks to the use of stretchy neoprene around the toe area, they adapt to the specific foot length.
