OP should chime back to clarify his needs, but if he has what he says he has, he needs lift/support and NOT a 'zero drop' or flat shoe, which is pretty much every normal flat skate shoe...
The term zero-drop refers to the angle between the heel and the toe of a shoe. ... Zero-drop shoes position the feet in their natural state, mimicking the same motion the foot makes when walking around barefoot i.e. FLAT
So when he asks for a shoe that has heel drop, like a running shoe, meaning lift, hence everyone suggestion the Boosentitz.
I wear both drop and zero drop for exercise, drops/proper lifting shoes for squats, zero drop for deadlifts, cross-trainers for regular shit, as well as hiking shoes in both styles depending on terrain (my knees like drop shoes tho when hiking).
For skating, I can't do drop shoes / Boosentitz, puts me on too much on my toes and fucks with board feel and usually forces heel slip...they just feel weird to me.
