I've been looking for an athletic shoe in black, my daughter told me then to the Model 420, 410 or advised. I could not decide long u have tested the models in stores, sneakers, running shoes and so fall anyway with every manufacturer and model different. I ordered it in 41.5 and broadcast on sandals / Ballerina always Gr 39 and in "fast shoes" Gr 40th This fits perfectly with me. The Model 410 I own from New Balance and there is enough for me Gr 40.5. Since I have the color navy / white taken and am very happy, that I can combine classic, I find quite appropriate for my age (40 plus!)
