I picked these up mainly for casual wear and beach days, and they’ve honestly been a great grab. They were comfortable right out of the box, which isn’t always the case with flip flops. The footbed has a little bit of cushion without feeling overly soft or flimsy. They feel supportive enough for running quick errands but still light and easy to slide on. The fit was true to size for me. They’re maybe slightly roomy in the toe area, but not in a way that bothers me. The straps don’t rub or dig in, which is usually my biggest concern with sandals like this. They also seem well made. The material feels durable and not cheap, and they have that simple Columbia look that works with shorts or just something casual around the house. Overall, solid pair of flips. Nothing flashy, just comfortable and reliable. I’d definitely buy them again.

This stove is very practical, I don't like to cook inside the house that's why I bought it. But you can use it wherever you want

Comfortable but runs large

These flip flops are very comfortable with a soft lightweight footbed that feels great to walk in. The fit is a little big with the footbed being the right size but the straps are way too lose causing me to accidentally kick the shoes off when walking up steps. Overall they are comfortable sporty flip flops but you may want to order a half size down.
