About this product
The Boost 350 V2 'Blue Tint' comes in a kids' edition with a Primeknit upper. Its knitted construction brings a visible textile texture, while the breathable design allows air to pass through. Laces provide the closure. This 2021 release combines those details in a children's shoe, with the fabric surface offering a different visual finish from smooth leather.
