Perfect toddler summer sandal!
Size: 6 Toddler, Color: Navy, Size: 6 Toddler, Color: Navy
My toddler loves them. Even though they are a little big for him (which I meant to buy a bigger size) the adjustable strap allows me tighten them enough so he doesn’t slide. Color goes with everything! Perfect summer shoe!

I liked them, toddler did not
Size: 7 Toddler, Color: Navy
I thought these were cute shoes. They were sturdy, protective, and flexible for little walkers. And they were pretty soft on the inside to wear without socks. Unfortunately, my two year old did not agree. He cried "don't like it" and immediately ripped them off every time I tried them on him. Maybe it's just my picky son. TTS/half size big.

Great looking shoe!
Size: 11 Little Kid, Color: Tan, Size: 11 Little Kid, Color: Tan
We got these sandals specifically for our Caribbean vacation over thanksgiving break. They run true to size but I did get them one size bigger to hopefully last for next summer as well. They look great on and go with everything! My son said they feel very comfortable on his feet and he likes easy on/off due to Velcro closure.
