Rubber boots are essential for an expedition cruise. Rubber boots are the ideal footwear for expedition cruises and are absolutely necessary for such a tour. With a good, insulated and solid sole, they will get you ashore dry-footed and even hikes can be managed with this footwear.
The vast majority of ships have rubber boots on board. Only on the very small vessels there are no rubber boots on board that can be rented.
If you book a tour on such a small ship and there is no room in your luggage to pack rubber boots, you may be able to rent them locally.
On Svalbard, for example, such a service is offered. More information here: rubber boot rental
