These slip-on fishing shoes from Huk are some of the lightest I’ve ever worn. They have very comfortable EVA midsoles and really light non-marking outsole. The mesh material is study but soft and dries quickly thanks to some drainage ports on the sides.
These are not as rigid as some other options but if you are looking for an easy-on and easy-off fishing shoe, that has a very comfortable fit and wears a little more comfortably than flip flops, this is the one. They weigh next to nothing, and I find myself slipping them on when I’m just getting tackle ready in the boat or heading to the lake to fish.
