From the manufacturer

The Big Kid's Momentum was built as a comfortable climbing shoe that accommodates the changing foot shape of growing kids. 

Whether it’s long, after-school gym sessions or weekend family pitches outside, the Big Kids' Momentum provides stretch where they need it, breathability where it matters, and high-performance rubber that won’t limit the rapidly growing skill set of the young crushers of the world. A micro suede upper, easy-entry hook-and-loop closure, and a round, soft toe box to accommodate changing foot shapes make the Big Kids' Momentum an ideal entry shoe for kids.
