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.
