Yes, you can wear water shoes at Universal’s Volcano Bay in 2026, and they are actually highly recommended for walking on the park's paths, which can get very hot and slippery. However, there are specific restrictions regarding the slides. While you can wear water shoes on the lazy rivers, wave pools, and most raft-based attractions (like Honu ika Moana), you are generally not permitted to wear them on body slides, such as the Ko’okiri Body Plunge or the Kala & Tai Nui Serpentine Body Slides. For these high-speed drops, you will be asked to hold your shoes or leave them in the convenient "shoe cubbies" located at the entrance to each slide's queue. Most guests find that a pair of high-quality water shoes or "water socks" provides the best balance of protection for the long walks between attractions while being easy to slip on and off for the more intense vertical drop slides.
