    When I found these for my son a few years ago I had no idea how wonderful they would be!! They last way longer than shoes of similar build...so much so that I plan on handing them down to my next youngest...they go everywhere..they are great in the water and he can still run and hike in them!! .please please please KEEN....make more colors and never discontinue these wonderful shoes!!

    Great Summer Sandal

    Quick to put on and take off and easy to clean. My almost 2 year old daughter's preferred shoes all summer long.

    These all rubber shoes are seriously AMAZING. I got them at consignment for my 12 mo old when he started walking and getting dirty outside but would have no problem paying full price, they are that worth it. They were my first ever Keens purchase and worth every penny. They are a dream to clean...if he gets muddy I just scrub them with a brush..all new.

    I purchased the rio for my 15 month old granddaughter. These are easy to get off and on. They have flexible soles and fit her chubby feet they are comfortable for her to wear all day, all summer long. I especially like to rinse them off and they are good as new. I recommend them for anyone with a toddler that won't wear shoes.

    My daughter wears these every day and I love them. We use them as her water shoes and they dry really quick. They've definitely had a lot of use and are holding up well. Just about to order the next size up for her.

    Great, light weight sandal but run big

    Great, light weight sandal. My son (toddler size 7) loves them but the heel strap should be adjustable as the sandal easily fall off. They run 1/2 size big.

    Great shoes! They look adorable and easy to put on, I can't wait for it to warm up so she can try them outside. I bought the purple ones and the colour is exactly as shown in the picture.
