LIKE BIRKENSTOCK Sandals, but Not the COST?

These 2 strap Sandals were used in my house only! They have the same ARCH SUPPORT & the exact same sole, pattern and the same 2 strap design. So why are they cheaper? I think because they don't have the name (BIRKENSTOCKs) on the buckles!?! Measurements: 10½" long & 3⅜" to 3½" wide. OH! I almost Forgot the MOST important part: I always APPLY the Expensive "CORK PROTECTANT" by Birkenstock to keep all my shoes "cork soled" shoes looking NEW! Thank you for visiting my crowded closet!
