Water sandals are a practical choice for someone who does not demand the high level of protection and traction offered by the water shoes. They are great for summer use and extremely comfortable because of the open design. However, the open design means they do not give a lot of foot protection, so it is important to be careful when walking or climbing in slippery places.
Water shoes are the most versatile option with the ability to give traction and toe protection similar to normal land shoes, but also the comfort and quick drying ability of water sandals. The look and style of these shoes vary significantly. They can look much-like a pair of athletic shoes while others can appear like a simple pair of sandals. Also, the versatile nature of the water shoes makes them a practical choice away from the water. For instance, they are great to wear for a land excursion that includes hiking in an area with plenty of rocky or steep terrain. Water shoes are particularly popular with canoeists.
Wet shoes are designed to solely work in a specific environment. They aren’t likely to be much use out of the water or give much versatility. This type of shoe has a thin sole which is fully acceptable in a raft or boat, but it is not a very comfortable option to walk on a hard surface, such as a gravel or rough parking lot. A great use for the wet shoes is for kayaking or canoeing because it helps to keep the feet warm in cold weather conditions.
Boat shoes are the most practical option for wearing on a yacht, fishing, pontoon, or other boat. They are basically a pair of moccasin style shoes that dry quickly and give great traction on a boat. However, these shoes aren’t practical for the very wet environment or activities such as kayaking or rafting.
