Riding hard in the mountains puts intense pressure on your feet. So we designed the Cosmic Ultimate SL to not only be lightweight, but also to deliver superior support and power transfer. It features updated patterning with a low-profile collar to reduce negative torque, and an ultra-low 6.5mm stack height. The Energy Full SLR Outsole is also 10g lighter than our previous outsoles. Every little bit helps in the hills.
The shoe has a bonded upper construction with ultralight mesh. 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. The key is an overlap construction combined with ultralight materials. It provides a snug, even fit with no pressure hotspots on your foot. And it's all held tight by a premium Boa IP1 closure system with micro-adjustment and quick-release.
