Abstract

Abstract Roller skates having a shoe or boot supported by a central support beam. The boot has an inside and outside corresponding to the inside and the outside of a user's foot to which it is designed to be removably attached. Each skate also has a first and second group of wheels in longitudinal alignment with the roller skate and in rotatable alignment with each other. The boot and groups of wheels are connected to a support structure. The first group of wheels is rotatably attached to the support structure and disposed to the outside thereof. The second group of wheels is rotatably attached to the support structure and disposed to the inside thereof. A first span between the most distant of the wheels of the first group of wheels is less than a second span between the most distant of the wheels of the second group of wheels. There are also brake means for slowing and stopping the roller skate when a user desires.
