The Krabbelmaxe was consciously modelled after a climbing shoe and features a flexible hexa4GRIP rubber sole. Forefoot and heel can move independently, thus involving muscles to ensure a healthy development of the foot. A long lacing area guarantees a secure fit, and the generous pull-on tab allows children to slip easily into the shoes. The rubber sole is sewn to the upper, making the shoe completely free of adhesives. It also guarantees durability of the shoe during the transition from crawling to walking.
