Bonita pero pueden mejorar ciertas cosas
Size: One Size, Color: Black/Silver
La compré hace dos meses y la e usado muy pocas veces de lo que me gustaría el color es bonito el diseño es precioso, la cadena se siente de buena calidad pero a pesar de que tiene poco que la tengo y que casi no la uso ya se empezó a despegar la “costura” (no sé el nombre correcto) de donde se dobla para cerrársela!

Stylish comfort you can wear all day!
Size: 6.5, Color: Chestnut
My wife has been been wearing the UGG Goldenstar Sandals for a few weeks now, and they’ve totally exceeded expectations. These sandals strike the perfect balance between comfort and style, and she’s gotten so many compliments on them!
Pros:
• Super Comfortable: The cushioned footbed feels like walking on clouds. Perfect for long days on your feet or casual outings.
• Lightweight: Unlike some chunky sandals, these are surprisingly light but still feel supportive and well-made.
• Adjustable Straps: The Velcro straps make it easy to get the perfect fit, and they’re great for swelling feet after a long day.
• Versatile Style: They look great with everything—from jeans and shorts to casual dresses.
• High-Quality Materials: Typical UGG quality—durable suede and solid construction.
Cons:
• Suede Requires Care: The upper is suede, so they’re not ideal for wet conditions and do need a bit of maintenance to keep looking fresh.
• Pricey: They’re on the higher end cost-wise, but I’d say the comfort and quality justify the price.
I’m really happy with these sandals. They’re a perfect mix of fashion and function, and I’d definitely buy them again in another color!

Best Sandal Ever
There is nothing about these that I don't LOVE. These are so comfortable and look so good. I have 6 pairs in every color. They r my absolute favorite. Run true to size. Listen to Amazon about sizing. They know... I am between size 7 and 7.5 and they recommended 7 and it was a perfect fit. I have not had any issues with the Velcro closure. Amazon has the best prices for UGGS.

Sandals that go with just about everything.
As a lover of everything Ugg, these didn't disappoint. They are some of the most comfortable shoes I have, very lightweight, and go with just about everything. They remind me of the old school Dr. Martens and I had a massive collection of those in high school. I have worn them quite a bit and you can barely tell as they are holding up extremely well.
