I bought these at a store, but my child outgrew them without wearing them. These are the successor model to the popular "570" known for its high cost performance. The midsole uses DynaSoft, providing comfortable cushioning and resilience. Rubber is strategically placed on the outsole for lightness, grip, and durability. The upper is a bonded type that feels good on the foot, providing comfortable support for everything from school to everyday wear. I only tried them on once when I bought them.
