I live in Coronado, CA in the very southwest corner of California and very near (maybe 400 yards) from the Pacific Ocean.  Our "winter" is mild and sandals are a common footwear!  Sandals are always "in season".
The sandals are a good fit EXCEPT that I have a "high arch" foot -- and the Velcro tabs barely reach around my ankle. I'm 6'-4" and weigh 235 lbs.
Also, these are NOT waterproof in comparison to the more expensive Keen sandals.
