Columbia always makes great stuff
Size: 14, Color: Espresso II/Black
Even with my flat feet these offer a lot of padding which makes these extremely comfortable. They increase my height about an inch haha. These are great for walking around the beach or just going for walks. The tread on the bottom of these make walking up hills where the surfaces are not completely even extremely easy and very grippy. Time will tell how durable these are, but so far they're holding up very well.

Comfortable Lightweight Flip Flops with Reliable Grip
Size: 9, Color: Black/Geyser, Size: 9, Color: Black/Geyser
These flip flops have an excellent fit with a cushioned footbed that makes them very comfortable to wear for long periods. The grip is strong on wet surfaces, which adds confidence when walking around pools, beaches, or after rain. The overall quality feels top tier, and the color looks clean and well finished. They are lightweight, and the sizing was spot on, making them easy to slip on and wear throughout the day.

Comfortable, Lightweight, and Easy for Everyday Wear
Size: 8, Color: Black/Geyser
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.

Great, durable toy
Color: Blue-Red, Size: Extra Large Size 5 (9")
I’ve had this toy for a while now and my dog absolutely loves it. I frequently bring it to the dog park with us and it’s also loved by other dogs. The ball is pretty durable. My dog is not a big chewer but other dogs that play and chew on it haven’t been able to pierce it yet. The handles are sturdy and also still intact. Overall a little pricey but in my opinion worth it.
