Style, Comfort
Size: 9, Color: Sand
If I could give a Ten Star review, I would. Hands down the most comfortable pair of sandals I have ever owned. I wore them 16 days straight while touring Italy. Comfortable and goes with all of your outfits. They pack well in a suitcase too. Light weight.

Wonderful
Super comfy and easy on and off, yet stylish imo! I could walk miles in these as a 56 yo and have worn them for three years! I hope they never stop making them. The only tweek I would suggest is to cover the footbed with leather or suede not cloth so they would last longer!

Lovely sandals!
I highly recommend! These are so comfortable! Right out of the box, they can be worn all day. The velcro-adjustable straps are great for making for a perfect fit. The aren't clunky to wear, even though they appear to be. They're super cute, in my opinion. The sock liner is textile, so feet feel good all day, not slimy, like leather and suede can sometimes make feet feel if socks aren't worn.

Cute and Comfortable
Size: 10, Color: Black
This is my second pair. I bought the sand color at my local Macy's. I got their last pair. I have issues with back pain and ankle swelling and pain. These are so comfortable I had to get them in Black. The adjustable straps are great. My feet are a little bit wider because of the swelling issues. So if you have very narrow feet these might be a little big. You might want to go down a half a size. But otherwise I wear a size 10 and they fit perfectly. I don't think the picture does the color justice. The black almost looks like velvet, it's very deep and rich. I wore them out today for the first time and got lots of compliments. The footbed is very comfortable with the memory foam. Lots of support. I noticed my back and ankle pain is much better wearing these. I've never owned UGG before. If these hold up really well and continue to stay comfortable, I will be purchasing other styles for fall and winter.
