Riding hard in the mountains puts intense pressure on your feet. That’s why we designed the Cosmic Ultimate SL to not only be ultra lightweight and stiff, but also to provide a higher level of foot stability and support.

The upper is made with a supportive TPU frame that’s laser welded to ultralight mesh panels. It has a low-profile collar to reduce negative torque, along with an ultra-low 6.5mm stack height that gives you a close connection to the pedals. The Energy Full SLR Outsole is also 10g lighter than our previous outsoles. Every little bit helps in the hills.

The last features a precise anatomic heel hold and a rounded toe box. It also has a heel retention system inside the structure, so there's no need for extra elements or weight to achieve a precise, personalized fit.

Usually, power transfer is all about the outsole. But we’ve created a new overlap upper that ensures every watt you produce goes straight into the pedals. It provides a snug, even fit with no pressure or hotspots. And the premium Boa IP1 closure dial gives you micro-adjustment for a precise fit and performance, plus a quick and easy release system.
