The modern classic of aggressive street skating. USD took it right back to the drawing board with the design of this skate, shattering all expectations and dismissing the UFS frame system, completely reworking our understanding of an aggressive skate and bringing the design back to basics. The unibody concept defines this unique design, creating the lowest, lightest skate possible with unparalleled energy transfer in every stride. One step back, two steps forward. With a single piece construction the weight is drastically reduced whilst the strength of the boot is immensely increased, youll never snap a frame again! The unibody concept allows for the widest H-block split possible, making this the best flat set up skate ever created, keeping you safe from wheel bite on all h-block tricks whilst still riding a full flat set up of fast and long lasting USD 61mm wheels. The skate is completed with the 2018 dual fit MYFIT liners. The stretchy neoprene toes allow for 2 sizes to be catered to with a single liner, giving perfect comfort and support in every session. rome steel balls, 2RZ rubber coating, synthetic oil
