Our modernized tread design is turned on an angle to create lateral flex grooves across the foot, which promotes anatomical movement. The tread blocks have also been spaced apart with recessed centers to reduce weight and increase flexibility.

We utilize a proprietary version of molded EVA-based foam developed specifically for improving comfort and reducing weight. UltraCush Lite is used in a variety of constructions and applications ranging from outsoles and midsoles to footbeds.

LXVI's proprietary fit that features a higher heel height to mimic the fit of running shoes, while maintaining a balanced feel. This allows for more heel cushioning and also puts the user onto the ball of the foot which gives a much more "lively" feel to the shoe.

Our proprietary heel and collar construction that uses a lycra coated neoprene cuff that is wrapped around a soft layer of open cell foam at its core for superior comfort and heel support.

This progressive upper panel construction replaces the need for conventional stitching, utilizing a thin film between panels that fuses them together when pressed and heated. This creates an extremely strong bond between the panels, which is more durable, lighter, and more flexible than conventional stitching.

This advanced liner construction improves the comfort and fit by enabling the shoe to conform and move with the shape of the foot. This free-floating liner, which is an extension of the tongue, is hidden under the front surface of the shoe, moving independently from the outer shell. This system increases airflow, breathability and reduces any chance of hot spots or pinching in the toe box.
