Which of the following footwear is least suitable for a rope rescue?

Rubber boots are least suitable for rope rescue primarily due to their lack of support and traction features essential for safety and stability in such operations. In rope rescue scenarios, personnel need footwear that provides a solid grip on various surfaces, including rocky or uneven terrain, which is often encountered in rescue environments.

Additionally, sturdy and securely fitting boots are crucial because they should offer ankle support and minimize the risk of slips, falls, and injuries during rescue efforts. Boots designed specifically for the rescue environment take into account the specific needs of rescuers, such as waterproofing, puncture resistance, and compatibility with harnesses.

Rubber boots, while waterproof, often compromise on the stability, support, and traction needed, making them less suitable for the dynamic and potentially hazardous conditions faced during rope rescues.
