The South Rim, a lightweight hiker with classic Danner style and proven. Danner comfort. We took the ultra-cushioning Vibram SPE platform from our best-selling Mountain 600 hiking boot and added a lightweight suede and mesh upper for breathability. The Vibram Fuga outsole features self-adapting lugs and Mega Grip for maximum traction, making the South Rim the ideal companion on the trail this summer.
