I have 4 boys and therefore I am always in the market for good sandals.  These Teva sandals are very good quality and I have always had very reliable experiences with Teva.  I have the Hurricane sandals for one of my older boys in size 3.  They work great for him and are easy to use but my 4 year old who is a size 11 cannot get these on.  The back strap does not adjust which is fine for bigger sizes because the strap across the ankle is bigger and can be pulled out much more.  In the size 11 the ankle strap can only be opened a little so it is really hard to slide his foot in.  Even with my help they are difficult to get on.  For smaller feet I recommend the Tyro or Psyclone which works much better instead of the Hurricane.  Other than that though the sandals are really great.
