I got a pair of the black high-tops and have to agree that they are very similar to chuck taylors. The sole is about a millimeter shallower than what you see of the yellow on the outside. They offer a fair amount of grip though as you can see the ribbing on the sole is very pronounced. Probably why the martial artists like them, handy for climbing walls and such too. I read a complaint that someone with a wide foot didn't like the high-tops as they were too narrow but this suits me and is why I bought them myself. I haven't tried the others so I can't compare.
