My kid loves them. He needed black closed-toe water shoes as a lifeguard at a waterpark.  He's on his feet all day, jumping in and out of the water towing kids out. These shoes are lightweight, quick drying, good traction, and elastic laces offer light cinching to keep shoe on (he's between sizes so it fits loosely without it).

Con: No Arch support
His feet and legs hurt after standing on his feet all day so we added a plantar fasciitis orthotic ($9), a 3/4 length shoe insert with heel, arch and ball of foot support under the shoe liner. The shoes stay wet longer but well worth the comfort.

Worth mentioning,
- one shoe cuff rubs the back of his ankle, likely a result of a looser fitting shoe in the water.  Had to rub on chafing stick or vaseline to lubricate the sore area.
- liner comes out each time you take off shoe
- large holes on shoe bottom allows water to drain quickly, but mud collects in holes from walking around.

Overall, these shoes are perfect for a visit to the waterpark, lightweight and dries quickly.
