They're cheap, they're simple. They are made of a softish plastic rubber material making them comfy with or without socks. If you don't like living in a running shoe world, these will set you apart from the crowd.

Fit is excellent (I'm a 12m mens).

I also have another style Native slipon which are equally comfortable and convenient.

I nice thin cloth liner would be nice, but without them, you have footwear to go from shore to water and quickly dried. And they replace that old faithful pair of cons that were so popular (and actually still are.

A fun and useful purchase.
