Went no 3 meters in the pool, as we were already on the nose. The sole is terribly slippery. Not only outside the pool, where you can really do neat hurt during a fall, but also in the water; It is almost two steps forward and slipping a back.
Optical liked the shoes already, and on the beach (grass or sand) they may not cause any problems and serve their purpose, but they are totally unsuitable's pool, for us it was a bad buy.
