Before this question is asked, it needs to be clarified a little bit. No one is going to use a diving fin for casual walking but once you get out of the water, you may want to traverse to a different area without taking your fins off. No matter how you slice it, though, no scuba fin will be designed for walking and they all will be awkward. However, open heel fins that accommodate boots may be the best way to go if this is a priority for you.
