SOO COMFORTABLE!
Size: 9, Color: Mustard Seed
SOOO COMFORTABLE! I LOVE UGGS! That foot bed is SO SMOOTH! I can't tell you how many pairs of REAL Uggs I have, I actually STILL have my first pair from over 35 years ago, and no one can believe they're that old! I keep all of mine in excellent condition! So when I saw these "summer" sandals I absolutely had to order them! I put them on and didn't want to take them off! Of course they fit like a dream! I always wear a 9 in all of my Uggs, these might run a tiny bit bigger, BUT they are adjustable! If you don't have a wide foot, you might want to size down. My feet tend to swell in summer, so I'm staying with my 9's. Price was great on Amazon, and they're REAL Uggs! LOVE the color! highly recommend!
