Abstract: An exemplary foot-warming system includes a device wherein a support assembly detachably mounts a battery pack on the upper surface of a boot to electrically power a heating element within the boot via an electrical cord that preferably passes through an opening in the boot beneath the mounted battery pack. The support assembly preferably includes a shallow retaining barrier, such as a frame-shaped sheet, for normally confining the battery pack to a predetermined position on the boot and a stretchable outer covering, such as an elastomeric panel, that forms a yieldable pocket within the barrier so that during a strong jolt to the battery pack or boot, the pocket can stretch to allow movement of the battery pack for reducing the level of shock forces transmitted and further can contract, after impact, to return the battery pack to its predetermined position.

Abstract: A ski pole grip has a timepiece sealingly and resiliently mounted within its upper end so that the rear surface of the timepiece is sealed by the chamber against exposure to moisture and the timepiece is resiliently movable with respect to the chamber in response to the selective application of force against the front surface of the timepiece. The rear surface of the timepiece includes selectively actuatable control elements for changing the time display in response to the resilient movement of the timepiece with respect to the chamber.
