We splurged on new flips for Florida...and due to plantar fasciitis and a big urging from our doctor/friend Liz, we settled on Chacos.
Love them already! They have all the casual hip knock-aroundness of flip flops but with hidden support (they call it a LUVSEAT footbed)! And in addition to comfort, the company is big on philanthropy. I just love their advertisement: Support your feet. Support our world.
Now that is true comfort.
