Is the Boatside good for wet boat decks?

Yes. It is designed for fishing and deck use, with an Omni-Grip LT outsole for traction on varied, wet surfaces. The open design drains and dries quickly.

How light is it compared with other boat flip flops?

Columbia lists 4.8 oz (136 g) per shoe in a women's size 7. The Omni-Grip LT foam outsole is stated to be 60% lighter than rubber, so it is lighter than most rubber-soled boat sandals.

Is the leather upper real leather?

Yes, Columbia describes a full-grain leather upper. It looks more polished than webbing straps but needs occasional cleaning and conditioning to hold up.

Can I wear it for everyday walking, not just the boat?

It works for casual summer wear, but the soft foam footbed and light outsole are tuned for comfort and grip rather than long-distance walking. For heavy daily mileage, a firmer walking sandal suits better.

Does it have arch support?

Columbia describes a soft foam footbed for comfort but does not specify an arch support. Shoppers who need firm arch support should compare with a contoured sport sandal.
