(0) Write a review
Guided by our True to the Trail philosophy, the Sun Kosi was made for going everywhere the trail leads, even when it’s not a trail at all. The most versatile in our Freeflow Collection, this performance sandal is built atop industry-leading R-MAT cushioning foam which serves as both outsole and midsole, saving weight while providing incredible durability, traction, and super-soft underfoot support. Adjustable, crisscrossed straps made of quick-drying webbing offer two points of adjustment to secure foot for all-day comfort.
A truly technical outsole made with lightweight R-MAT and blended rubber for durability and extra protection. This combination creates unbeatable grip with long-lasting rebound for an unbeatably smooth ride over even the most rugged terrain.
The map molded into the bottom of the outsole features Cataract Canyon in Canyonlands National Park, UT.
- Dual-density R-MAT midsole & footbed for exceptional grip, rebound, cushioning and comfort.
