Confident Walker, Runner + Jumper

Walking, running, jumping and generally being a chaotic ball of energy.This kind of activity requires a different approach in shoe design and Bobux I-Walks are specifically designed for this stage

A confident walker has a more developed, but still unique foot shape.

The i-walk range accommodates this, providing the best possible flexibility whilst adding grip for kids on the go.

As soon as kids can walk confidently they want to run and jump.
Taking off and stopping running, changing direction quickly, gripping the ground after a jump; at I Walk stage there is a diverse range of motion that feet must now accommodate.

  • Flexible sole in line with foot health best practice.
  • Premium materials. Full leather and advanced, lightweight textiles.
