Winter won't slow your kid down with Aery Warm GTX, Viking's most lightweight kids winter boot. A sporty and flexible upper features reflective details for improved nighttime visibility. Below, a thick EVA midsole that provides lightweight cushioning and insulation combines with a rubber outsole for solid grip. This focus on weight doesn't come at the expense of foot protection, which is why a warm liner and waterproof GORE-TEX membrane is included to keep feet comfortable no matter what the weather has in store. And machine washability at 30 degrees lets Aery Warm GTX SL keep looking good throughout the season.
