We had the shoes once already in use and I must say I'm thrilled! The children both had not even begin to come an excellent grip in shoes and slide around.
The shoes are very soft u. Pliable, even the sole, sit like a glove on the foot and keep the water well. Both children found it comfortable to wear. Tightening works well, the Velcro holds great (it is, as with Velcro usually to assume that this will change with the passage of time and the frequency of use, but at the beginning he makes a really good impression).
I had a number of purchases, the shoes due to previous reviews is smaller than the shoe size and so they fit exactly (instead of actually size 28 and 21, 26/27 and 18/19).
I can only recommend the shoes! Therefore 5 of 5 stars, even if they turn out too big, the quality convinced otherwise.
