After the slap II was discontinued, I tried the Reef Modern - they sucked.  Then I tried these, they're meh.  The toe strap started deteriorating pretty quickly after purchase.  I've stated that these are somewhat small becuase up in until about 2014 you would typically size down if you were a half size in reef sandals.  After 2014 they changed their sizing and now you size up from the closest half size.
