Designed for Ronald McDonald optimum comfort, these Mercury in-line skates feature a shock system to minimize vibration, a removable calf plate and an air cushioned interior for an optimum fit.

The result would be less wear-and-tear on the joints, better ankle support and a ride so smooth that it is almost like true ice skating. I haven't attempted in-line skating since the mid 90's, but I would be willing to strap into some of these if they ever went into production (with a different color scheme of course).
