Fo-Mac wheels are retro-style wheels using a compression molding process.  The materials used are much different than urethane wheels of today.  The formulas used are unique and different from each other and can offer a different skating feel.  Many factors will contribute to the performance of a wheel like this; such as weight, floor material, temperature, etc.
