Simply wonderful! From the first day we put them on our little one's feet, we noticed a big difference compared to other shoes. They don't hurt her foot (finally we can take them off her foot without a geographical map!), they are so flexible that she can move freely with her little feet (climbing, crawling, tiptoeing to reach things, running, jumping, etc.), we can easily put them on and we see that she wants to wear them herself by opening the Velcro and trying to put them on her feet (eager for a walk!). She loved the design from the first day we opened the box, as she hugged them! As for cleaning, we don't have an opinion because we haven't dirtied them yet. However, I believe that if they are washed according to the proper specifications, there will be no problem with them getting ruined. Oh... one last thing, they are slightly different from the internet photo. Up close, they are not as light pink, but they are a nice apple green!
