Some hockey skates inline speed skates include a Hi-Lo setup. Hi-Lo setups resemble a flat setup in that all 4 wheels touch the ground at the same time. Unlike a flat setup, however, different wheel sizes are used. The front two wheels will be smaller than the back two wheels. This is possible because of the location of the axles on the frame itself. One example is a Bauer frame that has two wheels in the front that are {{cvt|76|mm}} and two wheels in the back that are {{cvt|80|mm}}. Another example is a {{cvt|74|-|76|-|78|-|80|mm}} wheel arrangement. This drastically changed the pace at which inline hockey players accelerated. Furthermore, by transferring weight forward, the skater could sprint explosively off the toe section and reduce instances of falling backwards. If the hockey skate is used recreationally outside the arena, the skater will find climbing slopes much easier than on a flat setup. As inline hockey skate manufacturers design frames with varying axle hole placements or even raise the frame's back bolt to be higher than the front bolt nowadays, wheels of the same diameter (like {{cvt|80|mm|disp=sqbr}}) can be used entirely.

Beyond inline hockey, the Hi-Lo setup was an experimental component seen on K2's VO2 100 X Pro where the manufacturers believed that the two smaller wheels ({{cvt|90|mm|disp=sqbr}} each) in front would increase stability and rate of acceleration while the two bigger wheels ({{cvt|100|mm|disp=sqbr}} each) in the back would maintain high speeds. Essentially this K2 skate model married both wheel size properties. A Hi-Lo configuration on an inline speed skate employs three large sized wheels and a smaller sized wheel between the first and third wheels beneath the ball part of the foot (see [[Inline speed skating|speed skates]]). An example is a {{cvt|110|-|100|-|110|-|110|mm}} arrangement beginning front to back. This increases efficiency now that the foot pushes on a smaller wheel. The smaller wheel lowers deck height off the ground improving stability and keeps the frame length shorter improving maneuverability and comfort amongst speed skaters having a smaller foot size. This is desirable seeing how wheels on inline speed skates are enormous enough to occupy a lot of room in frames. Unfortunately, top speed for a Hi-Lo setup is far less than that for a flat setup where same sized large wheels are used.
