An adjustable and retractable rod apparatus includes an external pipe fitting, a multi-section rod unit and a positioning unit. The multi-section rod unit includes a first foldable rod and at least one second foldable rod, where the first and second foldable rods have the same outer diameter, and the positioning unit includes a linkage rope, a positioning component and a locking component, which are used to pull the external pipe fitting and the first foldable rod relative to each other. The linkage rope can be dragged, and the locking component and the positioning unit interlocked or separated. When the locking component and the positioning component are interlocked, the external pipe fitting can be connected to the multi-section rod unit in an unfolded state. When the locking component moves away from the positioning component, the first and second foldable rods of the multi-section rod unit are folded and in parallel relative to the external pipe fitting.

A wading stick is provided with an expanding elastomer support that prevents the stick from sinking into mud or other soft surfaces. The distal end of the support expands away from the stick when it contacts the soft surface. The support circumference increases in response to contact with soft surface and the increased circumference prevents the stick and support from sinking.

Attachment for a pole, in particular for a trekking pole, cross-country ski pole, Nordic-walking pole, or Alpine ski pole, comprising a substantially cylindrical sleeve (3) which can be fastened to the bottom free end (25) of a pole shaft (1), comprising a blind hole (22) open towards the top to accommodate the bottom free end of the pole bar, and an interchangeable element (2), which can be fastened to the sleeve in a detachable form-fitting and force-fitting manner. The sleeve comprises a head region (4) and an adjoining body region (5) extending downwards, and an outer thread (6) on at least one axial section of the body region. The interchangeable element comprises a tip or a rolling surface on the bottom end (21) thereof, wherein the interchangeable element has an axial blind hole (15) open towards the top for accommodating the sleeve.

A ski pole basket, typically made of a polymeric material, that includes at least one generally rigid portion with a specifically shaped perimeter/interface configured to interface with the heel lip of a ski boot is described. When the basket is attached to a ski pole, a skier can use the pole to press down on the ski boot while he/she removes his/her foot from the boot while in a substantially erect standing position.

A pair of first and second ski poles that can be connected to each other. The first ski pole has a first shaft with a first hand-grip at an upper end thereof and a first basket near the lower end thereof. The second ski pole has a second shaft with a second hand-grip at an upper end thereof and a second basket near the lower end thereof. The first and second ski poles can be interconnected by engagement of the first and second baskets to each other and engagement of the first and second hand-grips to each other. The first hand grip is mounted to the first shaft via a spring for limited axial movement relative thereto, and engagement of the first and second hand-grips is maintained by a biased force provided by the spring.
