for the last 10 year , I have be wear reef everywhere from Idaho to Baja , but they wear out so fast I switch to Rainbow which I have not worn since my high school day in Malibu . I have only be wear they a month or so , but they be break in nicely , and I anticipate they will prove durable . they say you can never go home again , but there be a tinge of yesteryear that be pretty sweet with my new Rainbow sandal . I think I find my tread of preference for the next 30 year . thanks Rainbow !
