other than the foot bed and liner as you said,the only difference is the spoiler (i think thats what its called?) the hot dogger has a rubber/padded bit at the back (were the boots sit on your calf) and maybe tongue has a stiffer flex but you could change that yourself you can also buy the foot beds on there own
Sorry that wasn't worded very well.
I ride park. Would the Classics work well for me?
