Since discovering this brand, I wear them all year round.  I have funky toe problems and appreciate the wide-open spaces that these sandals provide for my tootsies. They are incredibly comfortable while providing good support.  When the insole gets worn down, simply put in a "non-slip" sole pad and the shoes are like new again.  I buy them in lots of different colors so they'll always match whatever I'm wearing.  The only drawback is they're pricey.
