I have been vacationing in Siesta Key for 7 years and I always stop in at Comfort Shoes. They always have a sale going on with terrific prices on their Birkenstocks, plus other comfortable shoe brands. Very helpful, friendly, and knowledgeable staff. We come down annually for the Crystal Classic Master Sandsculpting Competition on Siesta Beach and a stop at the shoe store always yields great buys and super comfortable shoes. Be sure to check them out if you are a Birkenstock nut like me!
