A quick-attach/detach footwear-sole rocker system provides for wearers of inflexible-sole footwear such as ski-boots to attach one to each boot sole and enjoy pivotal motion while walking. Each rocker has an elastic loop which may be of bungee cord extending forwardly and one extending rearwardly, for tightly looping around a boot toe portion and heel portion respectively. Adjustment may be by placing knots in the bungee cord at desired locations fixing the cord relative to hole structure in the rocker. Use-ready transport and storage of the rocker system when not in use is provided: a hook on one loop provides for stretching the rocker system around a boot-top or ankle portion and attaching the loops together.
