The shoes are super sweet and complement the Shark series that I bought this summer for my son. So far we have only tested in the outdoor pool. He slipped not (the plates but there are also roughened) and on the meadow they gave great protection against the bees because anflogen the clover blossoms. As they fight on the slippery tiles in the pool, so I can not judge. The only downside, I have to give so far is processing the soles. Since stuck on a shoe partly a kind of film it, I have tried to deduct Here, then showed slight indentations on the sole. So far, that has still shown no impairment and the shoe keeps its promises.
