Bouncier than ever, while still delivering the same comfort and support that have made them a running icon, the Nike Air Zoom Pegasus 37 Kids Running Shoes have been fine tuned for kids from the adult model. Perforations through the upper work alongside engineered mesh to enhance breathability. As seen in the Pegasus 36 model, the new slimmer heel collar and tongue remain to work with the exposed Flywire cables to have the shoe conform securely around their foot even at high speeds. Updated from the Pegasus 36, the Pegasus 37 features a larger Zoom unit in the back with a thinner unit at the from for improved balance. The Zoom Air units work together with the Cushlon ST foam to keep them burning off their energy.
