Do you mean kickboxing as in western kickboxing meaning that there only kicks above the waist, the kicks are snap kicks not full power shin kicks like muay thai, they utilize more traditional karate/tkd kicking with front, roundhouse(w/top of the foot), back, crescent, spinning and side kicks.
Their hands are more boxing, there are no knees, elbows, and clinches like in muay thai. Try
