Great option for a great price
Size: 7.5, Color: Black
I love these sandals. They are well made, true to size and soft suede. They are lightweight and feel just like my UGG goldenstar sandals. (These are not as adjustable, so if you have narrow or wide feet, these may not be for you) These a great value for the money, especially for medium width feet. The strap across the toe is not adjustable, but fit my feet just fine. The ankle strap was a good length for me. And the Velcro is strong. These sandals are a great value for the money. I will probably start looking into kookaburra before I rush to buy the more expensive ones now.

Quality, good looking shoes!
Size: 8.5, Color: Green
Absolutely perfect fit, design, and color. I'm so pleased with these sandals and as always with this brand, I am not in anyway disappointed. These shoes are so comfortable right out of the box. They clean up very nicely, and last forever. I am so glad I got these before they were sold out.

UGG Comfort Without the Premium Price
Size: 9, Color: Beige, Size: 9, Color: Beige
These sandals are super cute and incredibly comfortable. They have that classic UGG look and feel, but at a much more approachable price point. The footbed is cushioned and supportive, making them easy to wear for extended periods. The straps feel secure without rubbing, and the overall construction feels solid and well made. They’re lightweight but still have a sturdy sole with good traction. They pair effortlessly with casual outfits and have that relaxed, elevated vibe UGG is known for—just without the higher price tag. A great value for both style and comfort.

Ugg comfy shoes
Size: 7, Color: Black
So comfortable and cute as well. I wore these the first time and had to have everyone touch them to see how the sole would squish. Fit well, and are lightweight as well.
