text: I wish I know Birkenstock from years ago but I am a new buyer. the sandals helped me so much I don't get tired walking for miles. 36 Narrow fits me perfectly in sandals, but 36 narrow in Boston clog was way large for me. It shipped from Germany so I cannot return them. I guess I will just have to go to Germany and buy a new pair 35 N there as it is hard to find my size here in the States. Thank you Birkestock non the less but please be aware that same size in these may end up bigger, it feels so much bigger that it is impossible to walk in them for too long distance. unless I add a layer.
