Used Birkenstock Arizona sandals. After years in the military and combat boots my toes and arches have corrected and my Birkenstocks no longer fit. My loss is your gain! This pair is my first and most worn pair. I do believe these sandals can be sent in to Birkenstock directly to be re-soled but these ones still have plenty of tread left. If these super broken in Birks aren’t for you, check out the other pairs in my closet that have barely been worn😊
