Arcus is the name of a cloud formation and this is exactly what this shoe feels like, with its low weight and high cushion. It 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 has higher density in the front 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. 

• Upper with bluesign 100% recycled PET Polyester 
• GORE-TEX lining is bluesign and meets Oeko-Tex criteria
• Insock liner made of bluesign, solution dyed, recycled polyester/Ortholite Hybrid
• Heel/Toe counters: Reinforcement of 50% recycled PET
• Midsole compound made with 20% BLOOM foam EVA

**WARNING!! For OUTDOOR USE ONLY. Wearing shoes with BUGrip studs indoors may cause significant damage to floor surfaces. **
