Macroblade 90 is the ultimate model for someone who wants to upgrade their older skates and skate a little faster. 90mm is a great size for wheels and the fit and support of the Macroblade 90 is incredible. The taller shoe design provides more stability when learning to ride on larger 90mm wheels, creating a better sense of stability and control while skating. The liner uses specially designed mesh for extra breathability, sock-like comfort and has all the cushioning you could need to make learning to skate much more enjoyable. The aluminum frame provides more power transfer and durability. The closure system is easy to use and secures the foot for maximum fit and comfort. The wheel/bearing setup is ideal for skaters to have the right amount of speed and control without going too fast. The brake is on the skate.
