I had a few years ago a pair of Reef sandals. Made of rubber. The were excellent - very comfortable and virtually indestructible. Only after two or three summers broke a toe webs. What is evident, however, because the mileage of the transgressor was remarkable. Last summer I bought then by another product (Havaianas). Also not bad. But there are just "flip-flops" and not "toe transgressors". So: If "flip-flops" or sandals with dock, then Zoris or Reef.
