Arcus is the name of a cloud formation and this is exactly what this shoe feels like, with its low weight and high cushion.

Arcus can withstand tough weather thanks to the waterproof GORE-TEX® Invisible membrane. The membrane is integrated with the upper material, making it even softer and more comfortable than a traditional membrane bootie construction. This shoe is for the user that wants to have extra cushioning, whether it might be for longer runs, recovery runs or when running with a backpack. To enhance the comfort and great running feeling it has a rocker midsole to reduce pressure on the forefoot and heel and aid the momentum forward - giving a smooth stride. The midsole is made of compression molded EVA which enables a natural dual density where the forefoot has a higher density - giving a more responsive toe-off. This gives great comfort on longer runs and yet provides responsiveness and a great running feeling. The BUGrip outsole has thirteen dynamic studs that provide reliable traction on all winter surfaces.

Sustainability highlights:
• Midsole EVA contains 20% BLOOM® foam, which is made from algae from overgrown lakes.
• The GORE-TEX® lining is bluesign® certified and meets the STANDARD 100 by OEKO-TEX®.
• Upper is made of bluesign® and 100% recycled PET polyester.
• The OrthoLite® Hybrid™ insole blends 5% recycled rubber and 15% production waste foam for 20% eco-content. It is lined with bluesign® 100% recycled, GRS certified and solution dyed PET polyester.
