The Rollerblade Women's Macroblade 90 Adult Fitness Inline Skates are the quintessential model for someone looking to upgrade up from their older skates and wants to skate a little faster. The 90-millimeter size is a great "go-to" size for wheels, and the fit and support of these skates is incredible. The higher boot design helps add more stability when learning to ride taller 90-millimeter wheels, thus creating a better sense of stability and control when skating. The liner utilizes engineered mesh for added breathability and sock-like comfort, and it has all the cushioning one could need to make learning how to skate much more pleasant. The aluminum frame adds more power transfer and durability. The closure system is easy to use and secures the foot to maximize 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.
