Can aggressive skates be used on a track or just ramps grinding rails %26amp; for extreme skating?
what do you meen on a track? as in the kind of track





I used to aggressive skate and I know that depending where you skate depends on wheels you use....you use soft wheels when at a skatepark with smooth surfaces that wont eat up your wheels...also the softer the wheel the more grip you get...when i street skated i used hard wheels cuz my softies wud ruin in just an hour....hope this helps





aggresive skates also beisde having edges for grinds are much heavier than normal cruising skates....that'd be the only difference....so again i hope this helps
