Impressive Mid Range Inline Boot— The Checker Formula


The formula is designed, developed and tested by Asian Champion Ping Su!!


Carbon Fiber base

The formula used a very good ratio mixture of carbon and grass fiber to provide a very good supporting for the skaters. On the base, we used 9 holes mounting system in order to provide more choice for skaters to set their frames up.


Last Design

Our last design is specially made for thin legs, the ankle supporting area is smaller than the normal boot in the market. We are hard to heat mold from a wide boot to fit a thin than make a thin boot to a wide skater. With our last, it has a better support for thin skaters and the big skater can overcome the problem by heat molding the boot.



The protector is placed inside , outside and the toe area of the boot, it provides a full protection of the boot from crashes.

Heat Moulding

The formula is a very moldable boot, you can reshape easily with an oven or a heat gun.
