I love these shoes. They weren't on sale (darnit) but indeed they are worth it. They are very flattering, super comfortable, and easy to put on with the Velcro fastener. I was hoping to find a true navy but these are very dark and can almost pass for black except when paired with black pants - then the blue becomes evident. I normally wear a 6.5 and purchased the 37. The shoe box indicates that a 37 compares to a US size 6. I don't think so... these are closer to a size 7 - a tad roomy for my 6.5 foot but just a tad. If you are a true 6, I would suggest a 36. These are my second pair of Riekers my recent other purchase is the ballet inspired Mariah 53. I am now a fan of this brand for style plus comfort. Now just give me a true navy please :-)
