Thanks to kybun on Mount Everest
From injury to world record
An ankle injury almost forced US extreme athlete Tyler Andrews into retirement. After an operation, a long recovery phase followed, during which kybun shoes played an important role.
“The shoes are very comfortable. I always wear them between my intense training sessions for recovery.” The extreme athlete notices that the elastic, springy sole of kybun shoes takes pressure off his feet, knees, and hips with every step.

About Tyler Andrews
Tyler C. Andrews, born on May 4, 1990 in Concord, Massachusetts (USA), is one of the most versatile extreme athletes in the world. He specializes in trail running, ultramarathon, and mountaineering and holds over 85 world records on some of the most demanding routes on Earth.
His career did not begin without hurdles: At the age of six, Tyler was diagnosed with a rare and life-threatening blood disorder - aplastic anemia. After successful treatment, he fought his way back to life and started running. He studied mechanical engineering at Tufts University and developed from an average recreational runner into a world-class athlete.
After years in marathon and ultramarathon racing - including victories at the Vermont City Marathon (2014, 2017, 2018) and a silver medal at the 2016 IAU 50 km World Championships - Tyler shifted his focus to high-altitude sports. Since then, he has set world records on Kilimanjaro, Aconcagua, Mount Fuji, Manaslu, and many other peaks.
