yup. i have DKs and one of my friends has Hot Doggers. his liner a bit thicker than mine and has the ankle power wrap, which will make them perform better and last longer. Then again, i bought mine for less than half than he paid for his (win).
but seriously, just like everybody on NS says, before you ask this question get fitted!!!! it would be one thing if you had actually gone to the store, got fitted for both, and are asking because your feet fit both and you want to know if its worth the extra 100 bucks. but it would appear that you aren't. so get fitted. then come back.
