True to size
Size: 9.5, Color: Tusk
I want to start off by saying I ordered a 9 and 1/2 and these fit perfectly so they are true to size. They are fairly comfortable in the heel isn't too high but is wide so they're very stable to walk in. They look great and can be styled in a variety of ways I have worn them with jeans but also a nice sundress and it works both ways. I've been wearing these for several months and they've held up really well and still look great.

Daughter ranks it 5/5. I rank them 4/5 due to heel comfort.
Size: 8, Color: Black, Size: 8, Color: Black
My foot is 9.44 inches long which usually places me in a 7.5. For this chart, it suggested the size 8. It's a perfect fit. The back zipper is easy enough to use. You don't even really need to undo the top strap once you have it adjusted to your preferred spot. My foot is narrow to normal around the heel and I'm wider in the toe box. These heels accommodate that well. I have plenty of room around my toes. The toe strap isn't smashing down either. The shoes seems well-made. The straps do not have a threads hanging. There's no sloppy glue drips around the bed. The bottom is strong and the heel is solid. I'm not a huge fan of thicker/chunky heel looks usually. I like the skinner heel styles mostly but ... there's a big positive to the chunky heels. They're very easy to walk in. Great heels for non-formal occasions. The bottom is not slippery. The cushioning around the toes in very nice. My only complaint is that the cushioning by the heel feels inadequate- especially at this price. It feels like you're walking on a block of wood. For that reason, I gave them to my middle schooler. She's thrilled. She pranced around the house in them testing them out for herself. She adjusted well to walking in them and she finds them comfy.

Lucky Brand womens Herrika
Size: 9, Color: Smoke Grey
These shoes are some of the comfiest heels I've ever worn! The heel actually has a nice height to it, but it's at a gentle slope that feels very comfortable. The heel itself is thicker, which makes it easier to walk, and I love the ankle strap for added security. The shoe's construction is solid, the materials are durable, and the zipper at the back of the ankle moves smoothly. I got the smoke grey color, which I think is really more of a lighter skin tone color, so I don't really agree with the name, but the color is accurately represented by the photos on the product page. This is a great neutral shoe that will pair with many different outfits. It's high quality and versatile, so I think it's well worth the cost. I love my new shoes!

Well made, true to size, comfortable, and attractive looking!
Size: 12, Color: Black
Wife was wanting a new pair of heels for a work party she has coming up and I happened to see these and thought they strongly resembled what she was looking for so I got them as a surprise for her. They arrived a few days ago and she tried them on that night and wore them around the house and to work a couple times to see how she likes them. So far, she is extremely pleased with them! She said they fit perfect and she's had no issues with comfort wearing them all day for work. She really likes the wider heel as it gives her more stability. Her favorite thing so far though has been all the compliments/comments she's getting from the other ladies in her office about them.

Lucky Brand nailed it with these sandals. The craftsmanship of the leather is top notch. I love the look of the crossover straps, they add a chic touch to any outfit. The fit is fantastic, I ordered my usual size 9 and found them to be perfectly true to size.
