Sizing info in the images.
The GH Inline figure frames replicate the rockered profile of ice blades and use narrow wheels to achieve an "on ice" feeling. Height adjustable toe stops allow you to better control your jump spikes and pivoting footwork. This frame can use any brand of standard adjustable 5/8" American/US threaded aftermarket toe stop, which gives you the freedom to control rebound and gives you purchase and style options when they need to be replaced.
Sizes 1 – 5 have 3 wheeled frames
Sizes 6 – 9 have 4 wheeled frames
