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.

cute and durable

these are great fit and quality. Very easy for on and off. good for wide toddler feet. my son loved them so much he melted down when they no longer fit - wish they made them in larger sizes. they held up well. only thing that fell apart after several uses was the lining on the sole peels out and has to be repositioned to stay in place when putting the shoe on.

Slightly Questionable

I really like the design of these shoes and the large toe box area. I did a lot of research on quality shoes for waterplay and these ones stuck out to me. However, my son seemed very irritated by these shoes as they would leave prints on his inner foot. He seemed very uncomfortable while wearing these shoes. My son never has clothing/shoe sensory problems, but for some reason these shoes did it for him. Unfortunately, we no longer have them due to them being uncomfortable and causing red marks.

Best Toddler Shoes

These shoes are among the best we've tried! They're durable (survived a whole summer of activities), easy to clean, and simple to put on. Plus, they look great! They run true to size, are wide, and flexible for little feet. Highly recommended!
