I'm very satisfied with the Chuck Taylor II shoe. I've worn the original Chucks for over 30 years and will continue until my dying day. The Chuck II is not a replacement for the original, but it is another option. It does provide better support, better build quality, and a better insole. It seems to be built on a last that is similar to the shape of the original, which equates to similar dimensions. However the upper material is thicker and more rigid, which to some may be uncomfortable, especially if you wear your shoes too small.  Basically, if you are a size 10, don't buy a size 9.5 because Amazon can't get you the color/style you want in a 9.5. In fact, if you deviate on size, deviate a half size up, but don't deviate down and you'll be satisfied like me. Will buy again (and have already).
