Rocker soles with a slight upward curve in the forefoot have been around for many years. The design is intended to aid forward propulsion and a natural walking gait. With the WK400 Keen has taken this design to the extreme. As well as more of a curve at the front than most rocker soles the shoes also curve up at the back. This continuous curve is meant to make walking “feel like rolling”.
Wearing the WK400s feels odd when standing still. Only the centre of the sole is in contact with the ground with both your toes and heel up in the air. This can feel wobbly! In fact if standing still it’s best to rock backwards and
