The term 'EXPANDS EXCESSIVELY' can be summarized by the crossword solution 'PADS', which stands for Pressure-Activated Dynamic Support. This is a type of cushioning technology used in footwear and other products to provide extra support and comfort. It works by using pressure-activated foam that expands when pressure is applied, allowing it to absorb shock and reduce impact on the body. This technology is often used in running shoes and other athletic footwear to help reduce the risk of injury.
