The On Running Kids' Cloud Sky 2 Trainers in Green are the everyday lifestyle version of On Running's iconic Cloud silhouette — built for children who want the On Running look and feel without the performance-specific construction of a dedicated running shoe. The Green colourway is one of the more distinctive options in the kids' range, giving the Cloud Sky 2 a fresh, fashion-forward edge that works as well with casual outfits as it does with activewear.

Available in EU 35.5 to EU 39 (UK 3–6.5) for older children and teenagers, the Cloud Sky 2 is unisex and part of the Mini-Me, PE Kit, and Activewear collections at Childsplay Clothing. The CloudTec® sole — On Running's signature cushioning system — delivers a noticeably different underfoot feel from standard trainers: soft on impact, firm on push-off. Made in Vietnam with sustainability credentials across the range, AW2026.

Buying Advice

On Running trainers generally run true to size, though children with wider feet may find the fit slightly narrow — sizing up half a size is worth considering. The Cloud Sky 2 is a lifestyle trainer rather than a performance running shoe, so it's best suited to everyday wear, school, and casual sport rather than competitive running or trail use. The Green colourway is a bold choice that pairs well with neutral activewear — grey, black, white, and navy all work — and stands out against more standard trainer colourways. As part of the Mini-Me collection, it coordinates with On Running adult styles for family matching looks.
