These shoes are great! I have low volume (narrow?) feet that seem to swim in other shoes. These fit perfectly, are very comfortable, and are also really cute.
I tried on some shimano shoes at another store to figure out what size I should get. Then I looked at the size chart for these and ignored it and instead ordered the same size as the shimano - 37. The shoes were then 2 half sizes too small. If I had just used the size chart they would have fit perfectly and would not have required me to drive over to the factory to exchange them.
The size chart is true to size. I wear a 6.5 street shoe size in most shoes and I wound up in a size 38.
