I wear a 7 birkenstock, my foot is 7.5 and a little wide. After reading reviews, I ordered 39. They are the same length as my size 7 birkenstock sandals. Definitely size up. These fit perfectly and the support feels like no other. I had a neuroma surgery and am very sensitive to shoes that don't fit right. These are wonderful!I will keep it but it is wide and loose.I really really wanted these shoes to be awesome…they were absolutely beautiful and stylish, but the moment that put them on I knew they were not going to work. I walked around the house in them and with the strap behind my heel my feet stayed in place but it hurt my toes, worn as a regular clog I could barely walk and they were not at all comfortable to me. Sadly, I returned them but bought a different style of Danskos (a Mary Jane style) that are the best shoes I’ve ever worn…I luv these shoes. After many shifts in my old ones I wore them out. And I'm talking years of 12 hr shifts. This is prob the most comfortable shoes I've ever had. You can't beat Dansko !I’ve been wearing Danko for 15+ years. They fit very well. No having to break in the shoe. Very comfortable from the moment you put them on. These particular shoes run small so get a size larger. I wear a 6.5 to 7 and chose size 7.5-8.5 and they fit perfectly.I have finally decided to give up wearing heals everyday for comfort :(Luckily I have a coworker who let me try on her Dansko shoes (different style), because I ended up ordering a 1/2 size smaller that what I typically wear. That being said they fit perfect, are quite comfortable and they look cute with jeans.Cute clogs but way too big in a size 7. I’m a 6.5-7 typicallyThese shoes are very uncomfortable. Gave me a blister when I wore them. I always wear this style shoe and have never had a problem with other brands. Normally, I find them very comfortable. I am very disappointed with this purchase.These shoes were purchased to wear at work, as I am standing most of the day on concrete floors. Recommended to me by a pedorthist as I was starting to have foot fatigue, sore arches and the beginnings of plantar fasciitis (not good). . Fit perfectly, ordered my usual size 39 (I wear North American size 8.5). Excellent support, also excellent at eliminating foot fatigue (I could do a 6 hour shift with no issues). Shipped very quickly, with a coupon for future orders, by ClogKingdom.com. Arrived to Canada within a week just prior to Christmas. The key to wearing Dansko is to understand these are perfect for those of us with high arches. If your feet are flatter, you will either experience a longer break in period while your foot adjusts, or find that they will not work for you. In which case, consider Birkenstock for flatter feet. The back strap on this style is super - keeps them on securely when climbing ladders etc. as I do for work. Look great with tights or trousers. Recommend!I bought these ones over the boxed ones because I love leather ,The ones I received have no leather in them at all,They are made of some kind of rubber,so they will not soften,so upset , They are not as described such a disappointment and if enough to stop me from buying online..Too short. My heel was handing outside the shoe.These are the classic Dansko fit. I work in health care and these shoes are a back saver!I am size 9, got size 41 think it will be loose but it was very tight that I couldn't walk . A friend told me to get 42 instead because she is siz 9 and she got 42 , i guess you need 2 size bigger , so will give it a second try
