发明名称 Apparatus facilitating walking in ski boots.
摘要 An appartus ( 1,2,3,4 ) that is to be temporarily attached to the soles of ski boots, whenever the wearer is not attached to skis and desires the ability to comfortably walk or desires protection for the sole of the ski boots. The preferred embodiment generally composes sandal type soles ( 4 ) made of a resilient, elastic springy material which aids in the natural walking action by alternately compressing and releasing, adding energy to the step, thereby aiding walking while wearing ski boots.
