These shoes are absolutely perfect for aquafit classes.  The fit is a challenge.  I read the other reviews carefully and also consulted the shoe fit advice.  I should NOT have ordered my normal closed shoe size.  I should have ordered a 7, not a 7.5.  My foot tends to the smaller end of 7.5 in length.  The fit solution is the only drawback.  Shoes are awesome with the holes in the bottom for draining water and walking into the locker room without squishing.
