New Balance Kids' 990 V6 Lace-up Sneaker - Supportive (Style KLL8)

In this review of the New Balance Kids' 990 V6 Lace-up Sneaker the bottom line is simple: these are a supportive, well-cushioned everyday sneaker for active children who need structure and comfort. The shoe borrows running-grade technology for kids, so the single biggest reason to buy is the combination of responsive FuelCell foam and ENCAP midsole cushioning that delivers a propulsive feel plus lasting support for growing feet. The design balances performance details with a leather upper and reflective accents for everyday wear.

Key Features

• FuelCell foam: provides a propulsive feel that helps encourage forward motion during play and short runs.
• ENCAP midsole cushioning: combines lightweight foam with a durable polyurethane rim to deliver stable, all-day support for active kids.
• Leather upper: gives the shoe a more structured, durable fit that stands up to daily use and holds its shape over time.
• Reflective details: increase visibility in low light, adding a safety element for walks and trips to and from school.
• Lace-up closure: allows a secure, adjustable fit to accommodate different foot shapes and keep the foot locked in place.

Who It's For

This sneaker is ideal for parents seeking a durable, supportive shoe for elementary-age children who spend lots of time on their feet. The combination of FuelCell responsiveness and ENCAP support makes it a good pick for kids who need extra cushioning without sacrificing stability.

Those who should look elsewhere include families wanting the lightest possible play shoe or a highly flexible minimalist sneaker; the leather upper and supportive midsole favor structure over barefoot-style flexibility. If a child needs a very narrow or exceptionally wide last, trying sizes in person is recommended since customers report mixed sizing feedback.
