The ultimate stress test for Knitido toe socks

Extreme athlete Harald Lange

Harald Lange - Harry for short - is an almost blind extreme athlete who proves to everyone: Where there's a will, there's a way. The passionate toe sock wearer has been testing our new performance models under the toughest conditions since the end of 2014 and is setting the bar pretty high.

Harald Lange was born on April 5, 1980 in Hofheim im Taunus with severe optic nerve atrophy on both sides, which makes him completely blind on the right and leaves him with 5% residual vision and a 12-degree field of vision on the left eye. But that didn't stop him from pursuing his passion for sports. On the contrary: Harry turned his weakness into a strength.

Harry describes running as a "natural measure of his strength, ... a primal instinct." Obstacles only drive him further: Harry needs to experience for himself what his body can achieve and where its limits are. He is not only an excellent long-distance runner, but has also subjected himself to the toughest tests. He has proven to skeptics what is possible with hard training.

In 2015, for example, he completed the 6-day Sahara extreme race Marathon des Sables and published his experiences in the Moroccan desert in the book Highway to Hell. His achievements, but above all his perseverance, are a great inspiration. He motivates everyone not to be stopped by external obstacles. His motto: "Whether disabled or not, if you want to achieve a goal, always stay true to yourself, believe in yourself and the cause, and above all: never give up!!!"


Harry has now written several books, both for adults and children. But he continues to pursue his passion: running. All his latest reports can be read here.
