"I have stayed away from Birkenstock in the past because of their blocky style, even though I heard how comfortable they are. When I saw these new designs I was intrigued and ordered a pair. The shoe does run wide (I wear a regular width but fit into the narrow pair just fine). Some reviews say these run long, but I think they are true to size. Although the sandal fits my foot, the Birkenstock company suggests you have significant room from toes to top and heel to bottom. I am a half size and ordered a size down...in the future I will order a size up. And yes, these are COMFY!"
