lemme preface this by stating my CDPs have only been worn once....
CDP >>> '15s and it's not close at all.
-side by side, u can clearly see the distorted shape of the '15s. if u look down at them while on feet, again, u can clearly see the shape distortion on the '15s
-the tongue on the '15s is all short and stubby while the CDP tongues have the correct height. the '15 tongue sits alot shorter than the upper that extends up past the ankles
-the overall height of the '15s is too short
-quality of materials is clearly superior on the CDPs
-the cuts of leather/nubuck are substantially thicker on the CDPs, which u can tell when u look near the lace holes
-and lastly, the overall comfort is by far superior with the CDPs
i will snap some pics later, i'm busy coming down...
