These group of skates are for very advance skaters. 90mm wheels at this stage should maneuver easily at this level and allows users to navigate sharp corners at high speed and also gives them the option to go faster as and when. Skates at 100-110mm will provide lesser maneuverability but gives user an edge when travelling straight long distance. Skates at this level usually comes with lower calf support, hence, skaters need to be able to balance without the support like the other categories of skates. Skates are made from lighter material like carbon fibre to provide maximum performance.
