Yes, if you participate in the main attractions at Niagara Falls, your shoes will almost certainly get wet, and potentially soaked. On the Maid of the Mist or Hornblower boat tours, the heavy mist and "spray zone" near the base of the falls act like a localized rainstorm; while the provided ponchos protect your torso, they often channel water directly down onto your feet. On the Cave of the Winds tour (on the U.S. side), you are standing on wooden decks just feet away from the rushing Bridal Veil Falls, where the "Hurricane Deck" will leave you completely drenched from head to toe. In 2026, it is highly recommended to wear waterproof sandals with straps (like Tevas or Chacos) or light sneakers that dry quickly. Avoid flip-flops, as the decks can be slippery. Many travelers bring a spare pair of dry socks and shoes in a bag to change into immediately after the tour to avoid the discomfort of "squishy" walking for the rest of the day.
