The adidas Yeezy Boost 380 Infants dresses the sneaker’s re-engineered Primeknit upper in a complementary blend of grey and brown hues, resulting in a subtle design that’s interrupted by a streak of grey on the translucent monofilament window. The lightweight build is mounted on a full-length Boost midsole, encased in rubber and reinforced by a herringbone rubber outsole to provide reliable traction for little feet.
