I've swum with traditional all-rubber fins since the 1960s and I now have a pair of Gull Mews, which are full-foot fins made by Gull Marine Sports of Japan. They are excellent both in performance and in comfort. Gull fins are embossed with two size ranges, one for bare feet and the other for booted feet. My Mews are sized XL (46-47), foot length 28-29 cm barefoot, 26-27 cm booted, with plenty of room to accommodate my own broad feet. As I have no experience with Gull Mantis dry fins, Scubapro Jetfins or Hollis F1s, I'm afraid I can't compare my Mews with those models.
