I purchased these as pool shoes to have on hand for our guests.  I wanted several pairs so that each guest could have their own, and could leave them here, with their names written on them, for their next visits.  The shoes arrived with the box reeking of a very sweet, bug-killer odor.  Once the package was opened and the flops were put away in the guest bedroom closet, one could still smell them with the door to both the closet and the guest room closed.  They've been there for several days and there is still a faint odor.  I'm happy I got them well before we were expecting any guests.  I'm sure they'll be fine as they continue to &#34;cure&#34;.  Their design will help them stay on one's feet better than a regular flip-flop.  They do run quite a bit smaller than labelled, so I suggest buying them a whole size up.
