While you can physically hike the trails of Cinque Terre in sneakers, as of 2026, you must ensure they are sturdy, closed-toe walking shoes with a non-slip sole. Following a series of injuries and expensive helicopter rescues in previous years, Italian officials at the Cinque Terre National Park have strictly enforced footwear regulations. Flip-flops, sandals, and smooth-soled fashion sneakers are strictly banned on the main hiking trails, such as the Sentiero Azzurro (Blue Trail). If you are caught wearing inappropriate footwear by park wardens, you can face fines ranging from €50 to as much as €2,500 if you require a rescue due to a slip or fall caused by your shoes. In 2026, a standard pair of athletic running shoes with good grip is generally accepted, but "fashion" sneakers like Converse or Vans are often deemed insufficient for the steep, uneven, and often slippery stone steps. For the best experience, lightweight hiking shoes or "trail runners" are recommended, especially for the more challenging sections between Vernazza and Corniglia. Remember that these trails are not mere "walks" but actual mountain paths that demand respect and proper equipment to ensure both your safety and your wallet's protection.
