I wear a 6.5 (36-37) in shoes. I've bought Sanitas in the past and they were too tight that I had to use a shoe stretcher on the width. This time I bought these in a 38 to avoid the shoes being too snug and tight. I have wide feet...but they aren't that wide. These shoes are soooo comfy but they're made for really narrow feet. Length wise the shoes are too roomy for me but they fit better with thicker socks. Width wise these shoes are soooo tight in a 37. The 38 is still a little snug with really thick socks but I'll have to wear thinner ones which isn't a big deal. The color is sooo pretty though. The bordeaux color is nice with a wine red and silvery/blue colors all over the shoe. The design on the shoe is nice as well. I'm glad I bought the 38. These shoes are so comfy. I can wear them all day at work!
