I bought my son (8 years) the Flippers. After the first tests Here is my review. Delivery: fast and well packed Scope of supply: fins with special "shoe trees" delivered so that the shape of the foot is maintained. Everything was delivered in a resealable plastic bag with handle is ideal for driving on the beach. Description: The fins can be individually adjusted to the size of the feet. Through a "Click-Lock" the setting is retained. Although Verstellungsaretierung is not particularly high-quality workmanship and therefore stiff, but she also holds. The foot rest is provided back down with holes, so that the water can drain freely while the (soggy) feet not, can hurt as open other toward the front flippers. The tether is sufficiently resilient and stable. Although the rubber coating on the underside first promises a good grip, so she has is a little too smooth for Einsatzt on tiles, and therefore a bit slippery. The feed for the float is good. However, a comparison I could not make.
Conclusion: I can recommend the fins. You bring my son a lot of fun and no pressure areas or bruises on their feet, although he has worn more than an hour at a stretch.
