What's zero drop?
The drop of a shoe is the difference in sole height between the forefoot and the heel. Scientific studies conducted by our research lab (the SportsLab) have shown that a zero drop allows for a more natural stride, similar to a barefoot running stride. This natural stride allows for better absorption of shock waves when running and strengthens your kid's muscles and tendons in the long term.
Why should adults not run with children's shoes?
The children's shoes are specially designed to conform to the shape of their feet, which is different from the adult shape. For example, a children's size 5½ does not have the volume needed for an adult's size 5½ foot. Children have a longer and more narrow foot, and the shape of the shoe is specially designed to respect this feature of children, whose feet are still growing. What's more, there is not enough cushioning for adults for running use
