Made for Speed skating, and long distance! 
The specificity of the Marathon skates is that they provide extreme comfort with extra padding, and more support than usual speed skates, as the top of the boot is just over the malleolus, and features the SEBA Triangle Cuff. The 195 standard mounting allows lower gravity. Usual Wheels standards for Speed are 4x110mm, fast but still maneuverable at high speed, or 3x125mm for more inertia and general speed in straight lines.
