Great Sandals!  True to size excellent fit and finish.  i Highly recommend these as a much less expensive alternative to other "Fishing / Water sport sandals.  They seem well built, are very comfortable, and use high quality materials in the construction.
Tred pattern on the sole is very agressive, and are slip resistant after a day of walking around on abrasive surfaces, ie. sidewalk, to break them in.  They are kind of oily or silicone coated on the sole fresh out of the box.  Walk around with them before use on a boat!  Great product!
