Nice but runs small
Size: 7 Big Kid, Color: Navy
The sandals are nice and not to hard or flimsy but they are cut very small.

Solid Kids Sandals, Overpriced Like Most Kids Shoes 🌞
Size: 11 Little Kid, Color: Brown, Size: 11 Little Kid, Color: Brown
My son hasn’t worn these yet since it’s December in Indiana and sandals + snow obviously don’t mix. 😂 So this review is based on first impressions rather than long term wear. That said, these seem wider than a lot of typical kids’ sandals, which I REALLY appreciate since we tend to have wider feet in our family. #hobbitfeet The quality feels pretty decent overall. They’re described as lightweight, and while they’re not insanely lightweight, they do have enough weight to feel semi-sturdy and not flimsy or cheap. I like the style and color, and I think they’ll work well for my son once warmer weather hits. My main complaint is the price. At just under $24 at the time of this review, it feels a little high for kids’ sandals and for what these are. I really feel like $20 MAX would make more sense. Kids shoes are almost always priced like adult shoes, even though they clearly use less material, and that’s hard for me to understand and wrap my mind around. Overall, these seem solid for daily wear, I just wish the price was a bit more reasonable and affordable.

Great basic and timeless design
Size: 12 Little Kid, Color: Brown
These sandals are a great find! They’re super easy to get on and off thanks to the Velcro straps, which is a huge win for little ones learning to be more independent. The fit is adjustable and secure, so they stay in place well during all kinds of play. The cork-style footbed is comfortable and gives good support, and the overall design feels sturdy enough to handle everyday wear. They’re lightweight but still durable, and have held up really well so far. They also have a classic, versatile look that goes with just about everything, perfect for summer outfits. Overall, a reliable, comfortable sandal that’s great for active kids. Would definitely buy again!

Great option for boys or girls
Size: 13 Little Kid, Color: Black, Size: 13 Little Kid, Color: Black
This is really more of a unisex option for a sandal. I have sandals that look like this, and both of my children have worn this style. I ordered these for my daughter, with the plan to pass them down to my son if they're not too worn when she outgrows them. The style is very minimalistic, so it goes with lots of outfits. All the straps are easily adjustable, so you can get a good fit. I would say the length is true to size, but the width is maybe a bit wide. Nevertheless, the adjustable straps really help them fit well. They feel really sturdy and I appreciate that the sole has cushion to it. My daughter has worn these every day since I got them out of the closet and they're holding up well.
