The innovative sport sock 4 Grip was born through this method. “We asked ourselves how we could help athletes ergonomically by using our expertise,” explains Andreas Falke.

After talking to professional footballers, it quickly became clear what the athletes’ biggest concern was: that their feet shouldn’t slip in their socks and that their socks shouldn’t slip in their shoes, even in a sudden change of direction. That is what inspired FALKE to develop the perfect sport sock.

“It sounds so easy – we’re going to make a sock that doesn’t slip. But there is a lot of know-how that went into the production.” stresses Michael Klein.
