ARIZONA SFB SUEDE NARROW by BIRKENSTOCK has a simple yet iconic design that has made it a highly popular style for decades, and is what many consider to be the epitome of a BIRKENSTOCK sandal. The ARIZONA is a unisex sandal featuring a two-strap upper that can be adjusted using the sturdy buckles, a traction patterned sole, and an anatomically moulded cork latex Soft Footbed (SFB) designed to support the foot and guide it to it's natural position. This style features BIRKENSTOCK's soft footbed (SFB) which has an extra layer of cushioning foam built into the footbed. NARROW refers to the width of the footbed providing a narrower fit to accommodate for the differences in the shape between people's feet.
